Sports car manufacturer What Porsche is planning for the electric future

Status: 06/22/2021 9:24 a.m.

As a rule, Porsche tests new technology first on the race track – including a new high-tech battery. Because there are no suitable batteries on the world market, Porsche will produce them in-house in the future.

From Tim Diekmann, SWR

If you sit in the new Porsche Taycan, you don’t have to do without the usual sound. Although the first fully electric Porsche should glide almost silently across the street, it sounds either like a bubbling sports car or – when accelerating – like an intergalactic rocket. Porsche calls this “Electric Sport Sound” – because the Swabian car manufacturer does not want to deliver its newest vehicle completely without sports car noises. The luxury sports car, which Porsche sold 20,000 times worldwide last year, is only supposed to be the beginning of an electromobility initiative.

High-tech battery made in Germany

In just two years, every third Porsche should be equipped with an electric motor – as a hybrid or fully electric. For this, Porsche needs lots of powerful batteries. But they are hard to find on the world market, says Porsche boss Oliver Blume: “We need high-performance cells for our electric sports cars. But we can’t find them anywhere at the moment. That’s why we develop and build these cells ourselves.” The first battery cells are expected to roll off the assembly line from 2024, initially for around 1,000 vehicles per year. “The focus will initially be on small series for racing and high-performance vehicles. In the future, however, this is not just about racing cars,” explains Blume at the official presentation at the Porsche Development Center in Weissach. In the first step, innovative technologies are usually only developed for a limited high-tech application, “but once the innovations have proven themselves there, they will gradually establish themselves across the board. That must be our goal. At Porsche, that’s what we call it Principle: from motorsport to series production. ”

Range model Tesla

For battery cell production, the Stuttgart-based company is working with the German company Customcells, which it claims to be a world leader in the development of lithium-ion battery cells. The joint venture operates under the name Cellforce Group.

According to automotive expert Stefan Bratzel from the Center of Automotive Management in Bergisch-Gladbach, it is logical that, after Volkswagen, Porsche is now also relying on the production of its own battery cells: “The battery cell accounts for the largest part of the car’s added value, and it has a lot of innovation potential . Automobile manufacturers who develop competencies in this area have a long-term competitive advantage. ” According to Bratzel, Porsche should not chase after the competition for the US electric car manufacturer Tesla, but rather must lead the way as an innovator.

New battery technology promises many advantages

According to the head of electrochemical energy technologies at the Center for Solar Energy and Hydrogen Research in Baden-Württemberg (ZSW), Markus Hölzle, the batteries as we know them today should still develop their potential: “Everything can, must and will be improved Above all, however, the cost of battery cells must be reduced further. And the energy density must also increase so that the batteries become more compact. ” The ability to recharge quickly is also important. To do this, Porsche wants to work with so-called silicon anodes, which “has two major advantages over the previously used carbon: it improves the ability to charge quickly and increases the energy content,” explains Hölzle. But now Porsche must first show that they can do it.

But while Porsche is still planning the future, competitor Tesla is already building the world’s largest battery cell factory in Grünheide near Berlin and promises a production capacity of 100 gigawatt hours per year, a thousand times as much as Porsche’s subsidiary Cellforce Group.

Climate neutral by 2030?

The focus on e-mobility and the setting of climate targets is an important step for the brand, emphasizes car expert Bratzel. “Porsche is a brand that nobody really needs, but many people want to have it because of its positive image. And I believe that it is becoming more and more important for the Porsche clientele in particular to say: ‘I have a sports car and still drive in a climate-friendly way . ‘”

Climate protection has long since become an image factor. This also shows the ambitious goal of the Swabian car manufacturer to be “balance sheet CO2-neutral” by 2030 and thus earlier than Daimler (planned for 2039) or Volkswagen (planned for 2050).

Environmentalists are skeptical

The environmental protection organization Greenpeace is skeptical whether Porsche will really be climate-neutral by 2030. “Unfortunately, ‘climate-neutral’ on the balance sheet ‘usually means that in the end generously cheap CO2 credits are bought from offsetting projects instead of consistently reducing CO2,” says Benjamin Gehrs from Greenpeace. With its large SUVs, Porsche consumes an unnecessarily large amount of resources. Porsche must also get out of the business with climate-damaging diesels and gasoline engines faster and more consistently than before.

So will the Porsche 911 possibly soon hit the streets as an electric car? Unlikely. In addition to battery cell technology, Porsche is also working on the development of synthetic fuels, so-called eFuels, which are to be produced using renewable electricity. Artificial sports car sound, as in the Taycan, is then unnecessary. At Porsche, the first step is to advance research in the field of battery cell development. The federal and state governments support the project with 60 million euros

Time draws back to 2004. When Professor Xu Kaihua, the founder of GEM (Shenzhen GEM High-Tech Co., Ltd.), returned to Jingmen, not far from his hometown in Hubei, to start his own business with the first prize of Guangdong Science and Technology Progress Award, people would never dream. I thought that Xu Kaihua used a small waste battery to recycle, which opened the prelude to the battery recycling industry and also started the black-and-white battle between the “regular army” and the “guerrilla”.

“Car owners cannot find or are not sure whether the recycling point is formal or not. Some power batteries recycled from traditional 4S shops and other channels also flow into small workshops.” Yu Puritan, secretary general of the Zhongguancun New Battery Technology Innovation Alliance and chairman of the Battery Hundreds Association In an interview with Chuangyebang, he revealed the inside story of the industry.

The business of “small workshops” is booming, while the supply of retired batteries in 4S stores of regular car companies is constantly losing. This makes people wonder whether battery recycling and cascading use of electric vehicles is a good business?

In the face of a large amount of goods flowing into the black market, formal enterprises are forced to trade with “small workshops”. As the leader of domestic new energy vehicle battery recycling, GEM Chairman Xu Kaihua warned new players in the battery recycling industry:

“Don’t come in, it’s a waste of money. Only the top five in the industry can survive.”

However, investors don’t think so. Just last month, Bocui Cycle, a power battery recycling solution provider, has just completed tens of millions of Pre-A rounds of financing, and Lanchi Ventures has made an exclusive investment.

“ At present, the investment circle is paying too much attention to the battery recycling track. In fact, the capacity of the industry that has been approved for construction has exceeded the battery capacity. “The person in charge of a battery recycling company said.

Why everyone refuses to talk about battery recycling

Industry giants have invested huge sums of money, investors and entrepreneurs are gearing up, coupled with national policy support, it seems that it is only a matter of time before the battery recycling industry becomes the next outlet.

According to data from the China Automotive Technology Research Center, the total number of domestic power batteries retired in 2020 will exceed 200,000 tons (about 25GWh). Where did the 200,000 tons of retired batteries go?

However, when the reporter visited a number of car companies, power battery companies, and battery recycling companies, they found that most companies avoid battery recycling, and new outlets in the 100-billion-level market have even become “taboos.” As a leading company in the field of new energy vehicles in China, BYD has launched the layout of power lithium battery recycling very early. At present, BYD’s battery recycling channels mainly entrust authorized dealers to recycle used power batteries. When there is a customer’s request or when a scrapped vehicle needs to replace the power battery, the dealer will take out the power battery and transport it to BYD Baorong factory for preliminary inspection. If the used batteries can be reused and continue to be used, the used batteries will be further tested at the Baorong factory. These batteries will continue to be used in the field of home energy storage or base station backup power in the future. The reporter wrote to BYD, but the other party was unwilling to reply. Yu Qingjiao stated that in terms of battery recycling ecology, at present, car companies, battery recycling companies and battery manufacturers have not yet formed a unified pricing for battery recycling, and the recycling business model is not perfect. Car companies “peek-a-boo”, power battery manufacturers and battery recycling companies have also played “Tai Chi.” “We have communicated with the relevant departments of battery recycling and will not accept interviews this time.” The relevant person in charge of AVIC lithium battery told reporters. Qingyan, who has had technological innovations in the echelon utilization of power batteries, also said that the relevant person in charge also said that it can only provide an introduction to its battery echelon utilization technology. As for the business model and pricing model of battery recycling, it is inconvenient to answer. “Enterprises have avoided talking about the recycling and utilization of decommissioned power batteries, and they are less motivated. The main reason is that the technical route of battery cascade utilization is not clear.” said Lin Boqiang, dean of the China Energy Policy Research Institute of Xiamen University. The energy storage path, what direction it will take in the future, and whether it is economical, requires both government supervision and government policy support. According to the calculations of Battery China.com, it is estimated that by 2025, the recycling value of power batteries produced in the two directions of cascade utilization and recycling will exceed 50 billion yuan; its potential market value may exceed 100 billion yuan in 2030. The industry is waiting for the “wind.” However, the recycling channels of many formal and qualified enterprises are not smooth, and a large number of retired power batteries flow into the black market. Some formal battery recycling companies even have to cooperate with black market vendors to purchase batteries from the latter to maintain the operation of the factory’s machinery and business promotion. This has undoubtedly contributed to the prosperity of the black recycling market. While pushing up the purchase price, it has also increased the difficulty of making profits for formal recycling companies. “One is because the number of companies is small and the coverage of outlets is limited; the other is that small workshops often use the banner of’high-price recycling, on-site recycling’ to obtain more waste battery resources.” Yu Qingjiao said. Due to technical problems in small workshops, the recovery rate of effective ingredients is not high, and there is a serious problem of waste pollution. The market is still in a period of disorganization, and it is difficult to guarantee the profitability of recovery. “Small workshops” generally have several treatment methods after recycling the batteries. Among them, the most common is to disassemble the battery and extract precious metals such as cobalt and lithium for sale. The price of non-renewable cobalt metal reached more than 600,000 yuan per ton when the price of non-renewable cobalt metal was the highest. In addition, the “Small Workshop” will sell the batteries to low-speed electric vehicles, electric bicycles and other echelon utilization areas not advocated by countries after recycling, causing great hidden dangers to the driving safety of the latter. “Batteries are taken from the black market. The source of waste battery materials is very poorly consistent. There are batteries of all types and types. This poses a big challenge to engineering design and project operation. Some foreign countries’ compliance with waste The collection is well classified, which will reduce the difficulty and cost of later collection, storage, and transportation.” Lin Xiao, founder and CEO of Bocui Cycle, told Chuangyebang. Yu Qingjiao pointed out that the current policies and regulations are still in the exploratory period. Although they have released a clear signal to support battery recycling, there is no real system formed, especially the circulation legal system. Second, traceability management and other regulatory mechanisms need to be strengthened to guide the upstream and downstream of the industry chain to strengthen battery recycling collaboration. “The first is the unblocking of recycling channels. Car companies in my country assume the main responsibility for power battery recycling. Recycling companies need to strengthen close cooperation with car companies, and strengthen battery life cycle traceability with battery companies to reduce recycling costs; secondly, through technology Innovate, increase material recycling rate, and increase recycling revenue.” Yu Qingjiao believes that the battery recycling industry is still in the early stages of development, and scale is also a key factor affecting profitability. The state should guide, regulate, supervise and provide financial support. Is battery recycling a good business? Although the recycling channels of decommissioned batteries need to be improved, and the material recycling rate and recycling efficiency of batteries need to be improved, some companies have already begun to deploy battery recycling business and have gradually become the industry’s leading company. Bangpu Cycle is one of them. “The constant has something.” Directly in front of the desk of Li Changdong, the founder and general manager of Bangpu Cycle, hung these four Chinese characters written in seal script. In Li Changdong’s eyes, Bangpu recognized the battery recycling, and it lasted 16 years, which is the best explanation of these four characters. In 2001, Li Changdong served as the production plant manager at Highpower Battery Factory. At that time, most people only focused on the front-end production of the battery and the intermediate consumption link, and the recycling link was often regarded as “garbage picking” and “recycling tatters.” Li Changdong found that the profit of battery production is getting lower and lower, and the scraps and defective products generated in the battery production process are also difficult to deal with. Handing over to the Environmental Protection Agency for processing will require a huge processing fee, and failure to pay will result in substandard emissions. “Can these battery waste be recycled for subsequent recycling?” This idea often appeared in Li Changdong’s mind. So he quit his job in the battery factory and raised 500,000 yuan with his partners. In 2005, Bangpu Recycling was formally established, with Li Changdong as the general manager, focusing on the recycling business of consumer lithium batteries. In 2008, the promulgation of the “Circular Economy Law” provided policy support for the development of talents and technology for battery recycling companies such as Bangpu. More and more scientific research institutions and talents are paying attention to battery recycling. In 2011, Li Changdong decided to further expand the scope of battery recycling business. He began to focus on power batteries from consumer lithium batteries to extend the battery recycling industry chain. Source: Bangpu Cycle At present, Bangpu has formed four major industrial sectors: battery recycling, automobile recycling, minerals and new materials, specializing in the recycling and processing of power batteries (power batteries for electric vehicles), gradient energy storage utilization; traditional scrap car recycling and dismantling, and key components Remanufacturing; and the provision of industrial production and commercialized recycling service solutions for high-end battery materials and automotive functional bottleneck materials. In 2015, in order to develop a circular economy and form an ecological closed loop, CATL acquired Guangdong Bangpu Cycle, realizing a circular industrial chain integrating R&D, production, sales, and recycling. Bangpu Cycle has now become China’s largest recycling base for used batteries. In September 2018, the Ministry of Industry and Information Technology announced the first batch of “whitelists” of enterprises that comply with the “Industry Standards and Conditions for Comprehensive Utilization of Waste Power Batteries for New Energy Vehicles”. Five companies including Bangpu Cycle, GEM, Huayou Cobalt, Highpower Technology, and Guanghua Technology were selected. However, from 2017 to 2018, the battery recycling market is still in its infancy. The relevant person in charge of Ningde Times told Entrepreneurship that the number of retired power batteries from 2017 to 2018 was relatively small, and the types and regional distribution were concentrated. About 17,000 new energy vehicles produced during the “Ten Cities and Thousand Vehicles” period are the mainstay. The decommissioned power batteries are about 27,200 tons (1.22GWh), of which about 95% are lithium iron phosphate batteries. From 2019 to 2020, buses, rental and other operating vehicles that entered the market in the early stages have reached the mandatory scrapping period. Early private user vehicles have begun to choose complete vehicle scrapping due to factors such as the decline in power battery performance, the lack of spare parts for old batteries, or the high replacement cost. Retired. Starting in 2020, my country’s power batteries have begun to enter a wave of large-scale decommissioning. During the period 2021-2025, my country’s new energy vehicles will enter a stage of rapid growth. New energy vehicles that entered the market in 2014-2018 will enter a period of obsolescence. With the continuous expansion of the scale of decommissioned power batteries, some people believe that the use of cascades should be increased to maximize the effectiveness of decommissioned batteries. Some people also believe that as battery prices continue to drop, the cost advantage of cascading utilization will gradually disappear or even hang upside down, and it should be directly recycled. The 2020 battery survey report released by Bloomberg New Energy Finance shows that by 2030, battery prices may exceed 58 US dollars (about 370 yuan) / kWh, and the use of solid-state batteries will accelerate the process of battery price reductions. By then, the battery cost will even be lower than the cost of cascading utilization. “It needs to be divided into different situations, mainly with technical support, able to accurately detect the condition of retired batteries, select batteries with better battery performance (safety, cycle life, energy density, etc.), and use them in cascades, which is more economical; Those with poor performance are directly recycled to avoid hidden dangers such as safety.” Yu Qingjiao said. Three problems of power battery recycling At present, the power battery recycling model has two major trends, one is echelon utilization, and the other is recycling, dismantling and recycling. Echelon utilization is the dismantling and reorganization of used batteries and re-applying them to energy storage power stations, low-speed electric vehicles, small electrical appliances and other fields that do not require high energy density. It is mainly suitable for lithium iron phosphate batteries with longer life and more stable performance; Recycling is the extraction of valuable metal materials from waste batteries, which is suitable for ternary lithium batteries containing expensive metals such as cobalt and nickel. The recycling of lithium iron phosphate batteries faces the problem of poor economy. Echelon utilization is still in the stage of trial and exploration. The main reason is that the battery specifications and models produced by various manufacturers are different, which makes it difficult to recombine. The battery materials used by each manufacturer are different, and the battery life is different; the battery performance of each manufacturer is different, and the combination Later security is more difficult to guarantee. The relevant person in charge of the Ningde Times pointed out that the economic value of cascade utilization at the current stage is still low, and further technical and industry standards are still needed. The recycling and dismantling can be said to have formed a certain scale, whether it is from the national policy or the market scale, we can get a glimpse of its trend. Although both are positive trends, the problems they face are also extremely challenging. The current battery recycling industry is facing three problems in process technology, policy and profitability. The first is process technology. Whether it is echelon utilization or dismantling and regeneration, they are facing severe barriers. The current biggest obstacle to echelon utilization is the remaining battery life and performance evaluation. In general, the recycling technology is relatively mature, but key technologies and equipment such as the efficient extraction of valuable metals need to be upgraded, and the level of pollution prevention and control in the dismantling and treatment of waste power batteries needs to be improved. At present, hydrometallurgy and physical repair methods are the main technologies for the recycling of used power batteries. The comprehensive recovery rate of metal elements such as nickel, cobalt and manganese in hydrometallurgy can reach 98%. The second is the policy aspect. At present, relevant departments have successively issued systems and regulatory documents that guide and support the development of the industry, and have sorted out a clearer direction for battery recycling. However, how to further effectively manage, rationally build a power battery recycling system, effectively implement full life cycle traceability management, and guide the upstream and downstream entities of the industry chain to fulfill the responsibility of power battery recycling requires the government to consider the market and industry. Planning and overall planning. In 2018, the Ministry of Industry and Information Technology issued the “Interim Measures for the Management of Recycling and Utilization of Power Batteries for New Energy Vehicles”, which for the first time clarified the responsibilities of automobile companies, battery companies, and comprehensive utilization companies in the recycling process, and pointed out that automobile manufacturers bear the main responsibility for power battery recycling. Perform corresponding responsibilities in all links of power battery recycling to ensure the effective use and environmental protection of power batteries. Finally, it is difficult to make profit. At present, the batteries that have really entered the scrap stage are still the earliest batch of batteries when new energy vehicles first entered the market. The number is not that large. Among them, lithium iron phosphate batteries account for a larger portion, which is more suitable for cascading use. In terms of economic benefits, recycling and dismantling The benefit is not high. In contrast, ternary lithium batteries have greater recycling value. But the reality is that it will take time for the ternary battery decommissioning flashpoint to arrive. Currently, the retired power batteries on the market are mainly lithium iron phosphate batteries. Because they contain less precious metal elements, the recycling value of lithium iron phosphate batteries is not high. However, due to its good safety and long service life, it is suitable for cascading utilization. The ternary lithium battery contains rare metals such as nickel and cobalt, so it has a high recycling value. According to the current technical level of ternary lithium batteries, the capacity density of power batteries commonly used in electric vehicles is 260Wh/kg. According to this energy density, at 20,000 kilometers a year, calculated based on shallow charge and shallow discharge, the cycle life is at least 1,000 times . If used properly, it can be used for at least 5 to 8 years on an electric vehicle. In the battery recycling industry, several leading companies have formed a certain scale of regeneration processing capacity, and their technical routes are in a stage where a hundred flowers bloom. Relying on its subsidiary Bangpu Cycle, CATL has created an ecological closed loop of “battery production→use→cascade utilization→recycling and resource regeneration”. Bangpu Cycle will uniformly process the recycled power batteries for electric vehicles. First, the battery modules are completely discharged, the battery cells are separated, and then sorted. After testing and evaluation, disassemble the batteries that do not meet the echelon utilization. Disassemble and separate components such as the positive electrode, negative electrode, electrolyte and diaphragm, and then leaching and removing the electrode material, and then prepare the scrapped power battery into the precursor of the power battery positive electrode material through processes such as ion exchange, precipitation, and adsorption. . Bangpu’s existing capacity for processing waste batteries exceeds 120,000 tons per year, and the total recovery rate of core metal materials for battery products has reached 99.3%. Due to the continuous decrease in the cost of lithium batteries in recent years, the annual report shows that CATL’s revenue of lithium battery materials in 2020 is 3.429 billion yuan, a year-on-year decrease of 20.35%. Source: Grammy As one of the leading companies in the domestic battery recycling industry, GEM’s power battery recycling business only began to make a profit in 2019, three years after the initial production. GEM’s advantage lies in the start of the recycling and utilization of waste batteries. It has accumulated 20 years of experience. In addition, it also has industrial layouts such as home appliance recycling and end-of-life automobiles to play a synergistic role to drive the recycling of power batteries. At present, the flourishing business model and technical route of battery recycling make the future market prospects still confusing, and it is still unknown whether it can effectively solve the pain points of the industry. From the perspective of business models, the current battery recycling is more dependent on other businesses, the tiered utilization is mainly dependent on energy storage, two-wheeler PACK plants or battery factories, and the recycling is dependent on the hydrometallurgical plant. If a company survives only on ladders or regenerative businesses, it may lose money. “How to do the most effective echelon utilization, as the scale of retired power batteries in the market becomes larger and larger, the technical route will gradually become clear.” Lin Boqiang told Chuangyebang. Where are the opportunities for entrepreneurs? Behind the black-and-white war between the “regular army” and the “guerrilla”, a group of start-up technology companies in the battery recycling industry are quietly emerging. In 2019, Lin Xiao, Ph.D. and senior engineer of the Chinese Academy of Sciences, established Bocui Cycle to provide a full set of solutions for battery recycling. According to Lin Xiao, due to the domestic garbage embargo, the issuance of the European mandatory battery law, and the accelerated deployment of battery recycling, ESG and other industries abroad, it is hoped that new links in the power battery industry chain will achieve a strong East Asian power battery manufacturer. breakthrough. The company’s overseas customer demand exceeds expectations, accounting for more than half. The obsolescence cycle of domestic power batteries is also very urgent. As of 2020, domestic new energy vehicles have sold more than 1 million units for three consecutive years, and 900,000 units have been sold in the first May of 2021. “Three years ago, the first batch of electric vehicles with an annual sales of one million units was calculated based on the service life of 5-8 years, that is, 1 million vehicles would be scrapped in two years at the earliest, and the battery pack of each vehicle was calculated at 400~500 kg. Therefore, in the next three years on the market, more than 500,000 tons of waste batteries will be scrapped every year. This amount is actually quite large, and the recycling market needs to be prepared.” Lin Xiao said. In the battery recycling market, everyone hopes to have mature technology and equipment solutions that can be quickly replicated and promoted. If a national processing capacity of 500,000 tons needs to be built in three years, at least 100,000 tons will have been running well in two years. Production capacity, and there are 2-3 kinds of technical routes to choose from, it is possible to achieve five-fold expansion within a year. In other words, one year later, there will be at least 20,000-30,000 tons of mature technology and production lines that can be replicated for battery recycling. In addition, the ratio of “paper-based recycling capacity” and actual battery output is seriously out of balance, which is also a big “blocker” in front of start-ups. In Lin Xiao’s view, the battery has entered the obsolescence cycle for more than five years, leading to a large paper production bubble in the battery recycling industry. “For investors, many of the leading companies that are currently being recycled, such as whitelisted companies, have already been listed or do not need financing. At the same time, paper production capacity is too high and supply exceeds demand. The opportunity for entrepreneurs is that there are still No company can really do this well, and there are still opportunities to try innovation and breakthroughs, although many companies may be eliminated, just like the development of the lithium battery manufacturing industry chain in the past few years, from the hills to the top.” Lin Xiao pointed out. The business opportunities that will be generated in the field of battery recycling need to be paid attention to also include the realization of material regeneration through battery recycling, thereby realizing the closed loop of the industrial chain, and changing the existing industrial structure and profit distribution. The technical direction of recycling will gradually move closer to battery materials, because in essence, battery recycling is a collection of resource collection and material recycling. There will also be many new variables in the collection channels of battery materials and the direction of the material recycling industry. For example, after the battery exchange mode, the requirements for recycling channels will become weaker, but it will give rise to another industry demand, such as battery exchange equipment and batteries. Asset management, etc., and whether it is possible to directly recycle used batteries at the grid swap point. There will also be many new variables in the collection channels of battery materials and the direction of the material recycling industry. For example, after the battery exchange mode, the requirements for recycling channels will become weaker, but it will give rise to another industry demand, such as battery exchange equipment and batteries. Asset management, etc., and whether it is possible to directly recycle used batteries at the grid swap point. “We think that battery recycling will definitely have great technical and market demand. It is just the beginning. This is a big track where few Chinese companies can lead the way from the beginning. It is different from the chip, lithium battery manufacturing and other industries starting from the beginning. , We can take a different development path. Once we can continue to lead the recycling technology and industry at home and abroad, and close the new energy industry chain, we can open up basic industries such as energy, resources, materials, and transportation.” Lin Xiao said. Under the wave of global electrification, the prospect of battery cascade utilization and recycling is beyond doubt. “It’s only a matter of time before the market scale exceeds tens of billions, hundreds of billions, or even trillions of dollars. As the industry chain matures, some high-quality companies will definitely be nurtured.” According to Puritanism, despite the bright future market prospects, battery recycling still lacks uniform pricing, the recycling business model is not perfect, and “small workshops” are rampant, battery recycling is still a game among leading companies. “Without recycling sources, this business is not your turn.” “At present, for entrepreneurs, the business model of battery recycling is very important. After all, it needs to be profitable. However, it is not ruled out that some companies can make the capital market pay, but at least there must be some visible business models before the capital market is willing to pay. “Lin Boqiang said to Chuangyebang. For entrepreneurs, everything is still full of variables

More and more electric cars Boom for Battery manufacturer

Status: 06/17/2021 10:13 a.m.

The growing number of e-cars on the streets is causing the battery market to grow strongly. One EU country in particular can catch up significantly with its Asian competition.

From Oliver Feldforth, MR

For years it was talked about, now the boom in electric mobility really seems to be there. Electric cars are very popular at a leading Frankfurt dealership. One seller says that what is delivered to him can also be easily sold.

The electric cars have contributed to the fact that the corona pandemic could not harm the battery market in Germany. Last year there was an increase of 35 percent. “Above all, the volume of the market for lithium-ion batteries has increased enormously,” says Christian Eckert from the Central Association of Electrical Engineering and Electronics Industry ZVEI. Overall, this segment grew by 63 percent. And that is mainly due to electromobility.

The recycling rate should increase

A battery is only as green as the material and the electricity used to make it. Even the electric car is only as green as the electricity with which it is charged. When it comes to battery recycling, German industry is on the right track, said Christian Rosenkranz, Chairman of the ZVEI Batteries Association. The recycling rate for classic batteries is 80 to 90 percent, while it looks worse for lithium-ion batteries, which are in increasing demand. The industry wants to achieve a rate of 65 percent in four years.

Environmentalists see a need for action. “It is not only in Germany that we have to set high social and ecological standards for the production of batteries,” says Benjamin Stephan from Greenpeace. “The car manufacturers are responsible for this, but politics must set clear rules for all companies.”

Poland leads the way in Europe

Germany imports batteries. The manufacturers from Europe overtook the Asian competition for the first time last year. In Europe, Poland is the leading producer, in Asia it is China, according to Christian Eckert from the ZVEI.

And electromobility will continue to grow. Volkswagen sees it that way too. The car manufacturer plans to set up six battery cell plants of its own in the next few years. According to Ralf Brandstätter, head of the Volkswagen brand, by 2030 at least 70 percent of all new Volkswagens in Europe should be electric vehicles, in North America and China more than half.

Solid-state batteries as the technology of the future

The decision as to which drive for cars comes after the classic combustion engine seems to have been decided for the time being. “The battery-electric drive is the most efficient and significantly more economical than fuel cells and combustion engines,” said Benjamin Stephan from Greenpeace. “With the same amount of renewable electricity, a car with a fuel cell can only go half as far as a battery-electric one.”

In the case of car batteries, solid-state batteries are to replace lithium-ion technology. It does not require cobalt, which under questionable circumstances is mainly extracted in Africa. For environmentalists, electromobility is only part of the necessary turnaround in traffic. And so Greenpeace is also calling for a change in mobility towards an intelligent transport system in which bicycles, buses and trains play a bigger role

However, although the screen of the iPhone 12 series was upgraded to OLED, it did not have a high brush in the end, and the battery capacity was still slightly reduced, which also caused many people to be not satisfied with the iPhone 12 series, and then began to look forward to the iPhone 13, and said iPhone 13 is the “Thirteen Fragrance”.

Previously, some people predicted that the iPhone 13 series will continue to release the new iPhone time, that is, it may be released in September, which means that there are almost three months before the release of the iPhone 13 series.

However, although there are still three months, according to the news, the certification information of the iPhone 13 series models has appeared in the Eurasian Economic Commission (EEC) database.

Judging from the details displayed by EEC, the number of new iPhone models is as many as seven, namely A2628, A2630, A2634, A2635, A2640, A2643 and A2645. Combined with the previously exposed news, these seven models are still the usual four models. Models: iPhone 13 mini, iPhone 13, iPhone 13 Pro and iPhone 13 Pro Max.

However, due to the different network standards, these models are slightly different from the National Bank version A2653, A2656 and A2660.

According to the 3C certification information exposed by @数码闲聊站, the battery capacity of the iPhone 13 series has generally increased. Among them, the iPhone 13 Pro Max is 4352mAh, which is nearly 700mAh more than the 3687mAh of the 12 Pro Max, the iPhone 13 is 3095mAh, and the iPhone 13 mini is 2406mAh. .

In addition, the iPhone 13 will not change much from the iPhone 12 in general. According to the news from all parties today, the iPhone 13 will continue the right-angle frame design in terms of appearance, but the screen will have smaller bangs and a larger screen-to-body ratio. Big.

In terms of screens, the sizes of these four models are still 5.4, 6.1, and 6.7 inches, but the two models of the Pro version finally usher in the legendary high refresh, which supports up to 120Hz specifications, and will introduce LTPO panels. Support 1-120Hz adaptive refresh rate adjustment, which can save more power.

In addition, the iPhone 13 series will also upgrade the entire series to a new generation of self-developed A15 bionic chip. Although it is still built with a 5nm process, it will be better in terms of power consumption and heat dissipation, and 5G performance will be effectively improved.

VinFast is building electric car charging stations The Ministry of Finance has just sent a document to the Ministry of Industry and Trade, the Ministry of Justice, the Ministry of Natural Resources and Environment and the Ministry of Transport, to respond to tax incentives for battery electric cars. Proposals for tax incentives only mention battery electric vehicles (BEVs). Currently, according to statistics, battery electric vehicles account for about 1% of electrified vehicles in Vietnam. Electric vehicles include many types of vehicles. In addition to gasoline-powered vehicles combined with electric energy (including HEV, PHEV) and Hydrogen-fueled cars (FCEV), there are currently BEV (pure electric) battery electric cars. Completely electrically charged from an external source. The two types of hybrid vehicles move mainly with internal combustion engines, in parallel taking advantage of the benefits of an electric powertrain consisting of an electric motor with a battery. FCEVs have an advantage over BEVs when the charging time is short, but the production of water makes hydrogen fuel-powered electric vehicles only suitable for island nations, arid areas, and unsuitable for urban areas. big. Meanwhile, BEV battery electric vehicles have a minimalist structure, run short distances, can consume electricity everywhere, have great advantages in urban areas. With three types of vehicles HEV, PHEV and FCEV all use gasoline and gas, so they have more impact on the environment than BEV models. Electric cars are becoming an advantageous choice to replace vehicles using internal combustion engines, especially battery electric cars (BEVs). Many countries around the world have had preferential policies and tax support to prioritize the development and production of battery electric vehicles. According to the Ministry of Finance, Vietnam has a number of preferential policies for electric vehicles. Accordingly, electric cars carrying passengers with less than 9 seats are entitled to the special consumption tax rate of 15% (ie 10% reduction compared to cars of the same type using fossil fuels; 10-16 seats are allowed to be used for cars of the same type using fossil fuels. tax rate of 10% (5% reduction compared to cars of the same type running on gasoline) and the tax rate of 16 to less than 24 seats is applied at the tax rate of 5% (5% reduction compared to cars of the same type running on petrol). At the same time, the Law on Special Consumption Tax No. 27/2008/QH12 also stipulates the special consumption tax rate for environmentally friendly vehicles. Specifically, vehicles running on gasoline combined with electric energy and bioenergy, in which the proportion of gasoline used does not exceed 70% of the energy used by the vehicle, is entitled to a tax rate of 70% for vehicles of the same capacity. species. For cars running on bio-energy, the special consumption tax rate is only 50% compared to cars of the same type. Meanwhile, about the current registration fee, there are only preferential rates for buses using clean energy while there is no policy applicable to other environmentally friendly vehicles. To encourage production and stimulate consumers to use BEVs, contributing to reducing the emissions released into the environment by vehicles, contributing to the protection of the ecological environment and based on the outstanding advantages of vehicles. BEV, the Ministry of Finance is planning to propose new incentives for this model. An electric vehicle charging station in Ho Chi Minh City Specifically, incentives related to excise tax fall under the jurisdiction of the National Assembly. Therefore, the National Assembly must amend the excise tax law. The Government has also assigned the Ministry of Finance to preside over the overall assessment of the implementation of the excise tax policy on automobiles in the past time to study and amend the excise tax law accordingly. Regarding the registration fee under the authority of the Government, when there is a need to change, it will amend and supplement Decree No. 14/20216/ND-CP on registration fee. The Ministry of Finance said that in the past time, it has also received recommendations from a number of associations on adjusting registration fee rates to remove difficulties for businesses. Therefore, the Ministry of Finance is also evaluating the overall policy on registration fees and is expected to submit it to the Government in October. The Ministry of Finance also asked agencies to propose specific content on special consumption tax incentives and registration fees related to battery electric vehicles to summarize and report to the Government. Battery-powered electric vehicles currently account for a very small percentage in Vietnam. According to data from the Vietnam Automobile Manufacturers Association (VAMA), the number of electrified vehicles registered in Vietnam is still very modest, accumulating just over 1,000 units by the end of 2020. of which BEVs only account for about 1%, the rest are HEV and PHEV models. According to the Ministry of Finance, currently only VinFast invests in producing electric vehicles, according to reports, VinFast has now launched the first battery-powered electric car model. The factory has a capacity of 250,000 vehicles per year and the brand is focusing on battery electric vehicles with 9 seats or less and electric buses with 24 seats or more. Also according to the Ministry of Finance’s assessment, the biggest obstacle facing Vietnam today is the lack of charging station infrastructure, the main source of power for power supply is using fuel sources with high CO2 emissions, accounting for nearly half of the total mobilized electricity output, while the electricity generated from renewable energy accounts for a small proportion, about 4.3% and this is considered an unstable power source.

Magic 1: Make the scissors sharp

The scissors at home will become dull when used frequently, and will not be sharp at all when used to cut things. At this time, we only need to cut the outer skin of the battery with scissors, and the scissors will become sharp immediately.

Coup 2: Use it as a mobile phone touch screen pen

The weather in winter is too cold. Many people wear gloves, but what should I do if they can’t play with their mobile phones while wearing gloves? Because ordinary gloves cannot touch the touch screen of the mobile phone, we can use the waste battery as the touch screen pen of the mobile phone at this time. It is very flexible to tap the mobile phone screen with the negative electrode of the battery. Is it very practical?

Coup 3: Remove static electricity from clothes

Dry weather in winter is easy to generate static electricity, especially when we go out and touch metal door handles, we are often “electrically charged”. Although this static electricity does not harm the human body, it sometimes hurts not to pay attention. Moreover, when we put on and take off our clothes, static electricity is easily generated on our clothes. At this time, the battery can play a role. When you go out in winter, rub the positive electrode of the battery a few times on your clothes or touch the door handle to remove static electricity. Isn’t it practical?So we must carry a used battery on our body

After reading the three magical life uses of used batteries, they are simple and practical to make your life more convenient. Have you learned it? Try it now!

This tablet has an enlarged screen size of 8.7 inches, Dolby Atmos multi-dimensional sound technology, 8mm thin and 371g light. Galaxy Tab A7 Lite owns an 8.7-inch screen Galaxy Tab A7 Lite owns a large screen with a display size of 8.7 inches with a screen ratio of 1340×800 pixels, a thin screen border that helps the screen body ratio (screen body ratio) up to 81%. Solid metal frame design. Despite using metal edges and owning a large screen size, Galaxy Tab A7 Lite has a light weight of 371g, making it easy for users to hold. Up to 81% screen-to-body ratio The machine has a unibody metal frame design The sound on the Galaxy Tab A7 Lite is also improved thanks to a dual speaker system that supports Dolby Atmos technology to create surround sound effects to optimize the audio-visual experience. Galaxy Tab A7 Lite is equipped with Helio P22T processor (MT8768T, Quad 2.3Ghz & 1.8Ghz) with multi-application and graphics performance scores increased by 75% and 92% respectively compared to Samsung Tab A8. RAM capacity is also upgraded to 3GB. Galaxy Tab A7 Lite equipped with Helio P22T processor, 3GB Ram The battery of the device is 5,100mAh with 15W fast charging technology and Type-C connection port Samsung has integrated a battery capacity of up to 5,100mAh with 15W fast charging technology and Type-C port for Galaxy Tab A7 Lite, to give users a seamless experience. Galaxy Tab A7 Lite will officially hit shelves at smart device distribution stores in Vietnam on June 3, 2021, including 2 color versions: Cosmic Gray and Silver Galaxy.

Referring to the Galaxy M, we will probably immediately think of a very popular Samsung product in the past few years, but the boldest is probably just the extremely large battery capacity left. The machine is quite clumsy, the performance has to be reduced to save battery, the screen and the camera are only enough to use. But this will change on the latest Galaxy M12. The first 90Hz monitor in its segment Today’s high-frequency screen seems like a common device, but it is for smartphones priced above 5 million VND or more, so not everyone has the opportunity to experience high frequency scanning. With the Galaxy M12, Samsung is determined to bring this device down and popularize the high-frequency screen for everyone. Although other parameters such as resolution, color display ability, brightness are all very normal in the price range, it is undeniable that the 90Hz screen is too valuable equipment on this machine. The swipe and touch experience is very smooth, different from Samsung’s previous smartphones of this price range. Thought that the Exynos 805 chip would not be able to bear a 90Hz screen, but on the contrary, the machine performed very smoothly, even more than some machines costing more than a few million. And the scan frequency here is also self-adapting, meaning that depending on the content and user operation, the screen will automatically adjust the scan frequency up or down to make it easier to monitor and save power. If you’ve used Samsung’s AMOLED screen before, you’ll find colors a bit pale, but when you upgrade from another TFT or LCD phone, you’ll be pleased with the color reproduction on the M12. Exynos 850 is “tailored” One of the reasons why the screen on the Galaxy M12 is so smooth is because there is a solid foundation behind it. Specifically here is the Exynos 850 chip as “measured” for this machine. If last year’s Galaxy A21s used this chip but still had a bit of lag, then to the Galaxy M12, Samsung has optimized its software according to the M12’s hardware, overcoming that situation. When playing simple games like last year’s Galaxy A21s, Temple Run 2, … the device can play fine, and games that require strong configuration like Call of Duty or Asphalt 9, you must install at the lowest graphics level. 5000mAh battery with fast charging With a sufficient configuration, not too high resolution screen but with adaptive scanning frequency feature, Samsung confidently equips the Galaxy M12 with a 5000mAh battery that can be used comfortably for two days without plugging in a charger. Unless listening to calls and surfing social networks like Facebook, Tik Tok continuously, it is still more than a day. Galaxy M12 also has Samsung built-in 15W fast charging technology, which is anyway better than the 10W or 5W charger that some smartphone manufacturers provide for popular phones in the segment. Fully charging the device takes about 2 hours. Young appearance Previously, the Galaxy M often had a rather clumsy appearance, mainly coming from the thickness of the device, the colors were also not many accents. Coming to the Galaxy M12, you will have a machine with a thickness of 9.7mm and a weight of 214g, numbers that cannot be said to be thin and light but convincing enough for a machine with a large 5,000mAh battery. Samsung is also quite smart when it mainly uses soft curves to reduce the more awkward and angular parts. Galaxy M12 sold in Vietnam will have 3 colors including Attractive Black, Elegant Blue, and Trendy Emerald Green, all colors that are not too ‘hard’, still youthful enough and I especially like the vertical lines. The body combines tiny diagonal lines, making it feel better to hold, more friction, without leaving stains, scratch-resistant, these are all essential details for a machine. geared towards mobile usage as much as the Galaxy M. Camera is quite in the 3 million segment Galaxy M12 is fully equipped with all the most popular lenses today, including, wide angle, super wide angle, macro and depth. Experience fast, the image quality of the M12 is quite good from detail, contrast, focus speed, or color quality. Compared to competitors in the M12 segment, it will be marginally better in super wide-angle and macro image quality. Enough for you to use on long trips. Some photos taken from Galaxy M12: Photo: Quang Dong

The notable points of the device include: 8-core processor, 90Hz refresh rate screen, 5,000mAh high-capacity battery, 48MP quad-camera set, reasonable price. However, due to the high capacity battery in the mid-range price segment, the device will be a bit thick and heavy (9.7mm, 214g). Besides, the screen border is also a bit thick. The device has a large screen, 6.7 inches, HD + resolution. This screen is large enough for surfing the web, social networking, watching videos. The 90Hz refresh rate is rare in the segment, making screen surfing smoother. Most machines in the 3-4 million dong segment have a 6.5-inch screen, so this size of the M12 is large. Only two models Vsmart Active 3 and Joy 4, which were heavily discounted after VinSmart decided to withdraw from the market, have a FullHD + screen, higher than the HD + level of the M12. Despite being at a low price, the device is equipped with a 4-camera cluster, enough for most basic shooting needs. In which the main camera has a resolution of 48MP, a large aperture of f / 2.0. The 5MP ultra-wide camera has a 123-degree shooting angle. The 2MP macro camera allows users to focus at a short distance of only 3-5cm. In this segment, only Xiaomi Redmi 9T has the same 48MP camera as the M12. Other devices have lower resolutions. Meanwhile, the M12’s font removal camera with a 2MP sensor helps to measure the depth of field, creating photos that clarify the subject, blurring the scene behind. Besides, the camera also has a professional shooting mode, allowing deep intervention in the photography features. In addition, this camera has additional features to capture panorama, capture food. The selfie camera with 8MP sensor supports portraiture, focuses on the subject, blurs the background. This camera has additional beautifying functions, creating stickers, or adding color filters. Most of the M12’s competitors have 5-8MP selfie cameras, but a few Vsmart models as mentioned have superior configurations. The back of the device is made from a plastic shell, with a textured design to help eliminate the possibility of fingerprints. The rounded corners make it more comfortable to hold. The machine is quite thick, so some people will feel like holding it quite firmly. M12 has 3 colors black, blue, turquoise. One of the strengths of the device is a 5,000mAh battery, integrated with 15W fast charging technology. With this battery level, the device can be used comfortably for 1 day, or lasts for two days if used lightly. According to the manufacturer, with a full battery will help the device surf the web for 1 day, talk for 2 days and listen to music continuously for 3 days. The battery capacity of the M12 is at a high level compared to many competitors, but some devices like Redmi 9T, Realme C15 have a 6,000mAh battery. The device uses an 8-core Exynos 850 processor, clocked at 2GHz, 3GB or 4GB RAM, 32/64GB internal memory (card slot reaches 1TB). This configuration can hardly install too many applications or games, so users need to select the necessary applications and games to install. In general, at a price of nearly 4 million VND, the M12 is a reasonable choice when compared to many competitors. However, because it is aimed at new users, it will be difficult for the device to meet heavy games, or have too high requirements for image quality. M12 is priced at 3.49 million for the 3GB RAM / 32GB ROM version. The 4GB/64GB model alone costs VND 3.89 million.

This update not only brings new features, but also fixes a series of security bugs on iPhone to prevent hackers from taking over the device. Many iPhone users have complained about battery drain and overheating issues after updating to iOS 14.6. (Photo: GearCoupon) However, only a short time after using it, many iPhone users have complained about battery drain and overheating problems after updating to iOS 14.6. “After stopping charging, the battery life on my iPhone 12 Pro Max quickly dropped from 100% to 35% in a period of 4 hours. In addition, the iPhone 12 Pro Max also got hotter, so much so that I felt I see it when I have my phone in my pocket,” said one user on the iPhone in Canada forum. (Photo: NewsBeezer) Another person also said that the iPhone must be plugged in continuously after updating to the recently released iOS 14.6 version. Besides excessive battery drain, users also reported overheating issues even when the iPhone was in standby mode for several hours. Many people are also worried that poor battery performance can reduce the health of their iPhone battery. (Photo: OS X Daily) According to ZDNET, battery life drops after each update is a common occurrence, because the iPhone has to perform some important management tasks, so the first days after installation will appear this situation. . However, if this situation persists, it is possible that the iPhone or the software has encountered a problem. On the Apple support forum, some users have fixed the battery drain issue on their iPhone by deleting the Podcasts app. Some users have fixed the battery drain issue on their iPhone by deleting the Podcasts app. (Photo: Primakov / Shutterstock) Accordingly, after accessing Setting > The battery and looked at the Battery Usage statistics by app, these people found Podcasts to be the culprit that drains a lot of battery on iPhone. After deleting this app, the battery life has improved markedly. If the battery life on your iPhone is experiencing the same problem after updating to iOS 14.6, try the above method to see if the battery life on your iPhone has improved or not.

“After updating yesterday, my device only has 2% battery left, the case is 15%. Normally after 15 hours of not plugging in the charger, the battery in the phone is still 100%, the charging case can be low. 20%”, this user said the maximum battery capacity currently in the setting is still 100% after more than a year of use, will have to measure again. Many iPhone users report battery drain after updating to iOS 14.6. Illustration: 9to5mac. “I had the same problem on my iPhone 11. After updating to iOS 14.6, I woke up every morning and always found my iPhone drained. Yesterday, I turned off Wi-Fi, Bluetooth on my device, closed all apps and nothing The phone is fully charged at 6 pm, and the battery is exhausted at 10 am this morning even when not in use”, member userid42 reflect. On the forum MacRumors , member BR4DOKYBrazil said that not only does the battery drain faster, this person’s iPhone 12 Pro also heats up when browsing the web with Safari. Another member also reported the same situation on iPhone 12 mini after updating to iOS 14.6. “I made the mistake of not checking the Internet feedback about battery life before updating to the new iOS,” this member shared. iOS 14.6 was released about a month after iOS 14.5. On iOS 14.5, Apple has added a battery capacity re-measurement feature to the iPhone 11 series, helping the device measure the maximum battery capacity more accurately, overcoming unwanted battery drain. In some cases, re-measured results even allow a free battery replacement. Short-term battery drain after updating iOS is normal because the device needs to update Spotlight searches and clean up the system. However, iPhone users with iOS 14.6 are still constantly reporting battery drain even though this version has been released for more than a week. Currently, Apple has not yet responded to the battery drain on iOS 14.6. The company is testing iOS 14.7 with some improvements, but may release iOS 14.6.1 if it finds the cause of the battery drain and needs to be fixed soon. Users can restore factory settings to check if the device is still draining the battery. Why does Apple name Apple Watch instead of iWatch? Apple has many products such as iMac, iPod, iPhone, iPad. However, when it came to smartwatches, they broke the rules and named this product line Apple Watch.

Software updates Usually, you should update your device to the latest software. Software updates allow more secure devices to be able to handle bugs or any malware. Software updates often include advanced power-saving technologies, which means less battery drain. To check if your iPhone has received any software updates you missed, go to Settings > General > Software Update. When updating, you should do it over Wi-Fi and plug it in to a power source to ensure everything goes smoothly and save mobile data. Optimize settings This is also a way to preserve battery life. Two settings you can control to help save power are screen brightness and Wi-Fi. You can adjust the screen brightness to a lower level as well as activate the auto-brightness feature so that the phone adjusts brightness depending on the surrounding environment to save power by Settings > Accessibility > Display & Text Size and enable Auto-Brightness function. Using mobile data also consumes more power than Wi-Fi, so remember to take advantage of the Wi-Fi network when you need to connect to the internet. Enable Low Power Mode LPM has been around since iOS 9 as an easy way to extend iPhone battery life when it reaches 20% or less. To enable it, go to Settings > Battery. In the Control Center, you can also customize the controls for accessing LPM on/off by pressing a simple toggle. To customize the controls in the Control Center, simply go to Settings > Control Center. Check battery usage In Settings > Battery, you can also check the battery usage of each app you use and the health of your device’s battery. The battery usage settings that you need to care about in this section include Background Activity (background activity) under the path Settings > General > Background App Refresh; Location and Background Location under Settings > Privacy > Location Services; Home & Lock Screen (Home screen and lock screen) follow the path Settings > Notifications to turn off unnecessary notifications; and No Mobile Coverage and Low Signal (the device will look for a better signal when in poor coverage). Besides, you can also use airplane mode when the battery life is about to run out, as well as check the Maximum Capacity feature to see how much battery is left and activate Optimized Battery Charging to reduce battery aging. Plug and power on the computer to charge the device Apple recommends that when you’re charging your device via USB on your computer, make sure your computer is plugged in and powered on. Otherwise, your battery may be drained if the computer is turned off, in sleep or standby mode. Additional tips Removing certain device covers during charging may create excess heat that can affect battery capacity. Be aware that ambient temperatures that are too high may be too cold or too hot for the device which may affect battery integrity. If storing devices for a long time, store them in a state of halfway charge and power off. If the devices are stored for longer than 6 months, charge them 50% every 6 months.

Research on recycling solar batteries contributes to boosting the weekly economy in Vietnam (Source: Internet). Solar power is an inevitable trend According to Decision No. 2068/QD-TTg issued by the Prime Minister on November 25, 2015 approving Vietnam’s renewable energy development strategy to 2030, with a vision to 2050, electricity produced from Solar power will reach about 35.4 billion kWh by 2030 and increase to 210 billion kWh by 2050. According to the Institute of Energy (Ministry of Industry and Trade), on average, a solar power source with a capacity of 1 MWp will generate nearly 70 tons of waste after about 20-25 years from the date the source starts generating electricity. Thus, according to forecasts, the amount of waste from these solar panels can reach millions of tons. Nguyen Van Hoi – Director of the Institute for Industry and Trade Policy and Strategy Research (Ministry of Industry and Trade) said that solar power is an inevitable trend of Vietnam’s energy industry, bringing many benefits to economic development. – society of the country and play an important role in reducing greenhouse gas emissions. In Resolution No. 55-NQ/TW on orientation of Vietnam’s national energy development strategy to 2030, with a vision to 2045, it is clear that it is necessary to develop synchronously, rationally and diversify types of energy. quality, prioritizing the exploitation, exhaustive and efficient use of renewable energy, new energy and clean energy; Use energy economically, efficiently, and protect the environment. Mr. Hoi said that the promotion of renewable energy development should be placed in the overall context of solutions, especially in the treatment of waste from the development of this energy source. Solar battery recycling solution Talking about the experience of processing and recycling solar panels of countries around the world, Mr. Dao Tran Nhan – Economic and Trade Advisory Association (VICETA) said, the Korean Government has issued new law “Extended Manufacturer Liability Program to take effect from 2023”. Accordingly, the Korean Government requires domestic manufacturers and importers to pay a recycling fee, which is expected to be US$1.04/kg. Meanwhile, Switzerland takes advantage of materials and components that are still valid to use and destroys those that are no longer worth using, using solar panels as a source of raw materials for making electric vehicle batteries (such as automobiles). , motorcycle). Proposing solutions for processing and recycling solar panels in Vietnam, Mr. Dao Tran Nhan suggested: For the group of policy solutions, it is necessary to develop regulations on downtime and storage. or recycle solar panels and have clear binding regulations between the parties. For the group of technological solutions, it is necessary to develop specific standards and regulations for each type of battery and develop a regulation to monitor and control the quality of solar cells. In addition, it is necessary to have a mechanism to encourage recycling as well as to develop sanctions to punish violations according to regulations. Dr. Le Huy Khoi – Institute for Strategic and Policy Studies of Industry and Trade also offered some solutions. Firstly, it is necessary to strengthen the inspection, examination and supervision of the collection and treatment of expired batteries. Second, the environmental protection responsibilities of owners of production, business and service establishments must “collect, classify, store, treat and dispose of solid waste in accordance with the law”. Third, research, develop and soon form a construction environment management department to regulate and supervise the final management of solar panels. Fourth, develop mechanisms and introduce policies to encourage investment in building solar panel recycling plants in Vietnam. Fifth, there should be financial and credit mechanisms and policies to support businesses in a practical way. Sixth, strengthen propaganda on the awareness of using, collecting and recycling solar cells effectively. Experts agree that, for Vietnam, the volume of waste from solar panels is quite small compared to the leading countries, however, to ensure sustainable development, the State needs to study soon to have appropriate policy and mechanism related to the collection and treatment of waste from solar cells. From a circular economy perspective, this can become an opportunity for Vietnam to develop the solar cell recycling industry in the future.

This time started in the summer, the demand for cooling devices increased, leading to a dizzying increase in electricity bills, so solar fan models were sold on the market. They are advertised, instead of running on electricity like conventional types, this type of fan operates entirely on solar power. Specifically, each solar fan will come with a solar panel to help absorb sunlight and produce electricity to maintain operation. Depending on the type of panel, when placed in the sun, the fan controller will charge the battery, which takes 4-6 hours. After the battery is fully charged, the fan will work for 6-10 hours continuously, even on rainy days without sunshine. In addition, users can use grid electricity to charge the battery for storage and use. Solar fans are causing fever in the market this summer Currently, on the market, these fans come from many places such as: China, Korea, Vietnam, … with very diverse prices, depending on size and function. In which, the lowest price is about 200,000-300,000 VND (mini fan), tree fan costs 800,000-2 million VND. Many fan lines are being discounted by 20-50% to attract buyers. For example, the 20W mini solar fan line is being discounted by up to 50%, from VND 830,000 to VND 417,000; mini fan 3.5W X9E is 40% off, from 510,000 VND to 306,000 VND; The Sunisi FT-30 fan model is priced at 1 million VND, 50% less than the original price of 2.1 million VND; Korichi KRC 6300 fan model reduced from 1.2 million VND to 890,000 VND; Jenpect 220V fan model has the original price of 1.3 million VND, down 34%, now only 850,000 VND,… According to the advertisement of the staff of household electrical stores, compared to traditional fans, solar fans have many advantages such as: no electricity costs, no fear of sudden power outages in hot summer days. Not only that, they are also very convenient when going on a picnic or camping trip; can directly charge other mobile devices such as phones, flashlights, … via USB port, which is very convenient. Moreover, long battery life 3-5 years of use, battery capacity up to 12,000 mAh, using time up to 8-12 hours. With “divine” functions, especially without consuming electricity, this type of solar fan immediately caused a fever in the market and was sought after by many people. Mr. Nguyen Hung – an employee of an electronics store in Ho Chi Minh City – said that at this point, the demand for cooling fans has begun to increase sharply, in which the solar fan line is the best-selling model. . As at the beginning of summer, his shop sold about 300 solar fans, at the peak of last year’s heat, he sold up to 800 units. Many fan models are having super cheap prices to attract buyers Similarly, Mr. Hoang Van Binh – an employee of an electrical appliance store in Thanh Xuan (Hanoi) – also said that in recent years, the price of electricity has tended to increase, people have the need to buy and use electricity. Use energy-saving appliances and take advantage of natural energy sources. Therefore, from May, customers looking to buy solar fans are busier. Currently, he only has 15 more fans to sell out. According to him, this type of fan is often suitable for low-rise houses, level 4 houses rather than high-rise buildings and apartments like in the city. Because the fan and solar panels are separate, it is necessary to choose a location to mount the panels to catch the sun (roof, rooftop, balcony, front yard, …) then connect to the fan set. Therefore, with high-rise buildings, moving equipment is quite difficult. But Binh also admitted, when it rains, the charging capacity of the fan will be poor, so in the prolonged rainy season solar fans will not be able to promote their full benefits. At that time, the fan can still be used by the grid as usual. Talk to PV. VietNamNet, Mr. Le Van Kien – a technical staff member of an electrical appliance store in Khuat Duy Tien (Thanh Xuan, Hanoi) – shared, when buying a solar fan, it is necessary to pay attention to the lifespan of the panels. The origin of the battery is unclear, poor quality will make the fan’s performance worse, the fan runs erratically, the lifespan is reduced, and it pollutes the environment. Moreover, the life of the battery is usually only 2-3 years, then it has to be replaced at a considerable cost. In addition, the capacity of the battery will determine the operating time of the fan, the battery is designed with a high capacity, the better the charge will be and vice versa. Limit the selection of multi-function rechargeable fans that are equipped with lights, alarms or clocks… because these features consume power from large batteries, making it easier for the battery to fail faster. Users should not be greedy, but buying low-quality fans will have many potential risks, so consider when choosing and need to choose to buy products of reputable brands and addresses.

Wallpaper set has 6 different designs, sold on the author’s website for about 6 USD for 2 designs. The wallpaper above is inspired by the Apple Face ID icon. When the battery is full, the wallpaper will be a smiling face with blue rings around. Conversely, tired face with red ring will appear when the battery is below 20%. In the charge state, the wallpaper becomes an unexpected face with golden rays of electricity. The first set of wallpapers with 3 shades designed by Ben Vessey. Ben Vessey also designed an apple-shaped wallpaper. Wallpaper will show apple (intact, not bitten in half) when full battery and apple core shape when battery is depleted, simple smiley face is between 20% – 100% battery and a frown face with battery short. All designs are very simple and easy to understand. Ben Vessey shared, the design of 6 smart wallpapers helps solve two main problems. One is that in case the user plugs the charger cord incorrectly so the phone will not recognize the battery, then with smart wallpaper, users will easily detect it. The second problem is that smart wallpapers will report low battery status. “When using the phone, our subconscious mind often ignores the low battery warning of the device. My designs will help users avoid that situation, ”shared Ben Vessey. The second set of backgrounds are highlighted with apples. Previously, according to predictions from some technology experts, the new-generation iPhone products can be equipped with Pro Motion technology, 120 Hz refresh rate and 15-20% lower power consumption than iPhone 12. Specifically, the iPhone 13 Pro and 13 Pro Max models will be equipped with LTPO energy-saving screen technology. This screen technology has appeared on the Galaxy S21 Ultra and Oppo Find X3 Pro. The LTPO display can automatically adjust the scan frequency based on the content being played. For example, when the user is playing games or watching action movies, the screen will increase the refresh rate to 120 Hz. When the user is not in use, the screen of the machine will automatically reduce the scanning frequency to lower, helping to save battery power. According to some leaked sources, Samsung and LG Display are in the process of converting production from LTPS to LTPO screens, which could be completed in the first half of 2021. However, there are opinions that capacity to make LTPO screens lower than LTPS because companies have to add some manufacturing processes.

According to Apple’s release notes, the update provides an important security patch, which fixes two major vulnerabilities in the WebKit suite of apps that could allow hackers to break into a user’s iPhone. Apple recommends that users update immediately to iOS 14.5.1 as soon as possible. (Photo: iOS News And More) However, the recent version of iOS 14.5.1 that Apple released recently seems to continue to bring other troubles for iPhone users. Specifically, in a thread created by Reddit user LHG_93, this person complained about the battery life on his iPhone getting worse after updating iOS 14.5.1, even installing Resetting the device also couldn’t help. “Has anyone noticed that the battery life of the device is very poor after the iOS 14.5.1 update. Even reinstalling is not helping,” said LHG_93. (Screenshots) Below the thread created by LHG_93, many members on Reddit also said they are experiencing the same situation after updating to iOS 14.5.1. “I have, too, the iOS 14.5 update is better than iOS 14.5.1”, said member DRS-MICKY. “I also noticed the same thing. I’m using an iPhone 12 Pro”, according to member zangielv. “Using an iPhone 7 and also the same as the OP,” shared member PaulF1959. (Photo: iPadizate) “It’s hard to understand how, after 8 beta versions of 14.5 and then 14.5.1, battery drain continues to be an issue on iOS 14 … I also saw a lot of battery drain on iOS 14.5. first. I don’t understand why Apple didn’t fix this. My device isn’t even that old, it’s the iPhone XR. IOS versions 13.5-13.7 are better in terms of battery retention on the iPhone XR. After 8 beta versions, iOS 14.5 should have been much better, “said member xxGon. (Photo: ThinkApple) Not only was it complaining about battery drain, iOS 14.5.1 is also said to cause some iPhone models to have performance issues. Notably, this error seems to occur not only with older iPhone models such as iPhone 7, iPhone 11, … but also iPhone 12 Pro, iPhone 12 are also believed to have a similar situation.

Initially Leafy house The activity was planned to be carried out in two weekends (April 17-18), but the battery collected in just 2 days has exceeded expectations and still many people have yet to participate. Therefore, the project is extended by young people from April 19 to 25. Young people bring used batteries to the Leafy House in exchange for green trees Hoang Ai Nghi (in charge of the program “Exchanging batteries for trees”) said, as of the afternoon of April 24 (on the 8th day – PV), the program has received a series of batteries, including: primary batteries , phone battery, laptop, rechargeable battery … For every 5 pieces / battery given away, you will receive 1 green tree, a small stone lotus or cactus. “Over the past few days, we have welcomed many people to send batteries and take back trees. Tracking and knowing about the program through fanpage or sharing from friends, students, employees, parents or even children bring batteries to support the program ”, Ai Nghi shared. The activity of “exchanging batteries for trees” actively contributes to the transmission of the message of green living and environmental protection You volunteers join hands in the program In addition to the activity of “exchanging batteries for trees”, Many Leaf Houses also sell green products and recycled products By the end of April 24, the program had received more than 120,000 broken batteries and electronic equipment; donating 6,000 trees. The collected batteries will be sent to the gathering point of Vietnam for recycling to be disposed of most thoroughly. It is known that each battery thrown into the environment or improperly disposed of will contaminate 1 cubic meter of soil and 500 liters of water within 50 years. Once received, these batteries will be volunteered by volunteers Leafy house bring to the gathering point of the Vietnam recycling program for the most thorough treatment. On the same occasion (April 24 and 25), Leafy house also organized the activity “Exchange plastic bottles for recycling socks” to receive more recyclable materials. “Many Leaf Houses” known as a chain of social activities in terms of culture, education and environment, has been deployed in Hanoi City and recently Ho Chi Minh City. Next to the activity “Change batteries for trees”, Leafy house also received plastic bottles and paper, implemented a free book library in the form of “lending books by trust”, sold trees to raise funds …

Making use of recycled materials, Mr. Le Thanh Cong, security guard of Tran Quoc Toan Primary School (Phu Xuan commune, Tan Phu district) built a semi-automatic garbage sweeper, laser reflective theft alarm system. . These devices are currently being used at the school. In which, the materials for this garbage truck are all recyclable items collected in the school and in the bottle shed. This sweeper truck runs on battery power. Just charging 6 hours, this car will have enough power to sweep garbage for 10 days. In 2019, he, along with two other teachers in the school, created a laser reflective theft alarm system. This equipment is also made from recycled materials with the total amount of just over 100,000 VND. The special thing is that Mr. Cong only made a burglar alarm installed in the security room, but it works to report the theft in the entire campus thanks to the reflective mirror system. Or like Mr. Bui Van Nhi, a guard of Xuan Hoa Kindergarten (Xuan Hoa commune, H. Xuan Loc commune) has “invested” for many years to decorate and beautify the landscape around the school. Accordingly, he designed the baby’s fairy garden, zoo … he also tried to plant lots of green trees on the campus to create shade for children to play. In addition, Mr. Ri also takes advantage of his free time at night to make toys for the children. These are the models of means of transport such as cyclo, tricycle, car …; household items such as furniture, censer, stilt house … These toys are mostly made from cans of beer and soft drinks, they are not only meticulous, durable but also very beautiful. It can be said that, having the dedicated guard, wholeheartedly in work and passion for creativity is the luck of the schools. To encourage this staff to have the opportunity to contribute more requires the care and encouragement from the school administrators. At the same time, in the patriotic emulation movement, these employees also need to be paid attention to promptly commend and reward.

Professional solar battery cleaning worker for a project in the city. Ho Chi Minh Meanwhile, according to engineer Thanh, the current method of cleaning the panels is mostly done by investors, most of them are using water, available facilities and using a hose to wash them, this method is not technically correct. in terms of maintenance, because many areas have water contaminated with alum, hard water, there is a lot of organic matter, more dissolved metals… leading to further damage to the panels. “The effectiveness of the project apart from equipment, materials, installation techniques, the operation and maintaining the efficiency of the system is related to the cleaning of the panels. Keeping the panels clean is the key to maximizing output, increasing economic efficiency for investors, ”Thanh said. Solar power is booming in Vietnam, especially household investment packages, concentrated in remote and island areas in the South. According to the Vietnam Electricity (EVN), by the end of 2020, the total capacity of renewable energy sources will be 17,430 MW (up 11,780 MW compared to 2019) and accounting for 25.3%. . In which, there are about 8,000 MW of rooftop solar power and more than 8,400 MW of large farm solar power. Thus, according to investors’ calculations, the whole country currently has no less than 30 million solar panels operating in the whole system and will increase when many projects are under construction and about to be operational. Seeing this potential, a number of businesses in the South have added new services, which are professional cleaning of solar panels and package maintenance for solar power systems. the investors. Mr. Le Tran Khanh Vy – General Director of Nhat Hung Environmental Technology Co., Ltd. (Thu Duc City) – said that in the face of more and more investors installing solar equipment, the company opened more professional solar battery cleaning service, currently hundreds of customers across the country have signed contracts to participate in cleaning and maintaining solar power systems with this package. To meet the needs of customers, especially solar power investment packages in industrial form, the company is forced to professionalize by producing standard cleaning solutions, investing in specialized cleaning equipment. and has a team of professional staff in charge. “The solution that the company offers is to keep batteries clean by cleaning them regularly and properly; Check the water source, if the water source is contaminated with alum, hard water, contains a lot of organic matter, lots of dissolved metals, it must be handled; choosing a cleaning solution specialized for cleaning panels, because now there are domestically produced products with appropriate and safe prices, ”said Mr. Vy. On the market, there are specialized solutions for cleaning solar cells According to electricity experts, at present, many solar power projects are invested billions of dong, even more money, but the stage of battery cleaning and system maintenance is less concerned by investors properly. This leads to a reduced lifespan of the building, especially the heat collection efficiency of the panels is low, while if cleaned and maintained properly, the economic efficiency is not small. Mr. Huynh Duc Tien, living in Hoc Mon district, city. Ho Chi Minh has just signed a package contract with a company specializing in solar battery cleaning and maintenance of the solar power system with an investment of more than 1.2 billion VND nearly 2 years ago. Mr. Tien said that the cleaning company has specialized solutions, tools and techniques, so it is handed over to them for management because the cost is not much and it saves time.

POSCO, the world’s fifth-largest steel producer by production, said on April 14 that it would build a factory in Korea to extract lithium hydroxide, a key ingredient in electric vehicle battery (EV).

POSCO’s announcement said last week that the Board of Directors approved a plan to complete a factory in the industrial city of Gwangyang in southern Korea by 2023.

The plant, which will start construction in the first half of this year, is expected to have an annual production capacity of 43,000 tons of lithium hydroxide, enough to produce about 1 million electric vehicle batteries.

POSCO said they plan to import spodumene for the extract lithium hydroxide at the factory above from Australia.

In addition, POSCO plans to start building another plant near the Salar del Hombre Muerto salt lake in northern Argentina in the coming months. The plant is expected to have an annual capacity of 25,000 tons of lithium.

POSCO purchased lithium mining rights in Argentina from Australian mining company Galaxy Resources for $ 280 million in 2018. Currently, the steel producer has the mining rights for 22,800 hectares of the area.

According to POSCO, the site is confirmed to have lithium reserves of 13.5 million tons, enough to produce batteries for about 370 million electric cars.

The South Korean giant steel giant has stepped up its activities in the electric vehicle segment in recent years as part of its business diversification strategy.

In February 2021, POSCO Chemical, a subsidiary of POSCO, announced plans to invest 275.8 billion won ($ 248 million) to expand the production capacity of cathode, a key component for batteries. EV for a factory in Gwangyang.

In addition, POSCO Chemical also plans to set up factories in China and Europe to promptly supply cathode to EV battery manufacturers.

The EV battery market is on a strong momentum as automakers around the world are racing to convert to electric and eco-friendly vehicles.

This wave comes in the midst of tightening regulations on greenhouse gas emissions by governments – which scientists say is the cause of global warming.

When it comes to 5G mobile phones, the most pleasant thing is the internet speed, but the worst is battery life and weight. Most high-end phones on the market sacrifice battery life to reduce weight and improve battery life through super flash charging above 50W. I recently bought a new machine, Realme V13, which is thin and light and has long battery life. It gave me a new understanding of realme phones. No wonder my friend said that Redmi has another strong competitor. Some bloggers broke the news that this month Realme released a new Dimensity 1100 machine, lamenting that the donkeys of the production team are not so high-yielding. The focus is on the cheap machine, the price is very cruel, and it is indeed very exciting.

1. Appearance, thin and stylish

Closer to home, let’s talk about appearance first. The phone case uses a yellow and simple design, as always in the realme style, with the product model on the front and basic information on the back.

After opening the box a little bit tightly, you can see “Dare to leapfrog with 70 million young people around the world”. From this sentence, you can see a lot of information. Realme focuses on targeting young people. The global users are rounded to 100 million. Users Over 100 million is just around the corner.

Family portrait includes realme V13, transparent soft protective case, warranty card, quick start guide, SIM card pin, USB data cable and charging head.

The one I chose is a misty rain gray, the whole machine is a bit grayish black under different light, and another color is azure. Obviously, this color is inspired by “azure is waiting for mist and rain, and I am waiting for you”, the design The teacher’s idea is very clever, meaning that realme is always waiting for you.

The upper left corner of the front screen of the mobile phone is a front digging camera. The mobile phone comes with a film before leaving the factory.

The rear camera of the mobile phone looks like a four-camera matrix, but it is actually three cameras, one for a good-looking embellishment, mainly for symmetrical viewing comfort, and for OCD users to consider. In the lower left corner is the small logo of Realme, which does not use the big logo of Guofeng, which is quite satisfactory.

The middle frame on the right side of the phone is the two-in-one fingerprint power button. The side fingerprint and the screen fingerprint radish greens have their own loves. My friend thinks that the side fingerprint recognition is faster, but I feel that the gap is not obvious. The volume buttons are on the left side. To be honest, the volume buttons on my previous mobile phones were all on the right side. I still need to get used to it. The card slot adopts the mainstream super practical 3 card slot design, supports dual card dual standby and can expand the memory.

At the bottom of the phone, there is a precious 3.5mm headphone jack, so you no longer have to choose between charging and headphones when you only have a Type-C or Lightning port. Next to it are the microphone, Type-C interface, and speaker. Both the microphone and the speaker adopt a long strip design, which is more unique and easier to identify than the round hole. If it is placed in a row with the SIM card, it will not mistake the pinhole and the microphone.

The thickness of the body of 8.5mm and the weight of 185g must make you full of expectations for its battery. The thin and light body has a large 5000mAh battery. The battery life should be very reliable. It is a pity that the maximum support is only 18W. Charging, similar to the iPhone, is much better than Apple’s ancestral Wufu and Yi’an.

Second, experience, dare to leapfrog

After getting a new phone, after reading the appearance, the most important thing is to turn it on and check the parameters. In addition to the large 5000mAh battery mentioned earlier, we can also see that it is equipped with a 7nm process 5G processor Dimensity 700, standard 8G storage, AnTuTu running score of 356,000 points, this score is equivalent to two years ago equipped with Snapdragon Long 845, 855 flagship machines such as Meizu 16, or equivalent to the iPhone Xs equipped with A12, are very good.

Realme UI V2.0 based on Android 11 and ColorOS11 is backed by OPPO to enjoy the coolness, and the smoothness and cleanliness of the system continue the style of Color OS. With a large 6.5-inch screen, a smooth and high refresh rate of 90 Hz, and a 90.5% screen-to-body ratio, the screen display is smooth and smooth, making it smoother whether it is daily use or playing games. It’s a little regrettable that the chin is still a bit wide. It can only be said that the price is the same level, not too much beyond my expectations, and there is room for improvement.

The battery life level is very good. The 5000mAh battery really did not disappoint me. I can watch a whole TV series in one breath a day on weekends, and the continuous video playback lasts for up to 21 hours. Say goodbye to the anxiety of working hours during the day. Don’t worry even if the battery is low, turn on the super power saving mode, 5% battery can stand by for 34 hours, or chat on WeChat for 84 minutes, which is an exaggeration.

In terms of photography, the three rear cameras meet the basic photography needs. The 48MP main camera works with the camera’s 48M mode to record high-definition moments. The portrait blur lens works with the camera’s portrait mode to record TA’s beautiful images. The 4cm macro lens works with the camera’s super macro mode to explore close Distance to the world. The rear supports up to 10x optical zoom, no ultra-wide angle, and the front camera is 8 million pixels, which is quite satisfactory. For users who are accustomed to ultra-wide angles, they may not be comfortable with it. It can be said that it is difficult to change from frugality to luxury. If it’s the first 5G mobile phone for young people, it should be enough, shooting landscapes, people, and macro.

The sandstorms in Beijing made everyone insightful. It’s not a mobile phone imaging problem. It’s the sandy weather in Beijing. The color reproduction is more accurate.

The super macro imaging effect is still relatively clear and delicate.

Optical zoom basically meets the needs of use.

The 10X imaging effect in the figure below is still unsatisfactory.

Thanks to the Dimensity 700 blessing, the mobile phone supports 5G, is compatible with SA/NSA dual standards, covers the mainstream 5G frequency band, and supports two sim cards at the same time 5G online. As a thousand yuan machine, although I know that the gaming experience cannot be too high, some tests have been carried out, and the result is that more than 350,000 running points are not for nothing, and the gaming experience is not bad.

The average frame rate of King of Glory is 59, and the average fluctuation is 1.56 frames. The jungle, laning, and team battles are very stable. There is no obvious lag during the game. The body consumes power, 20 minutes of game, power consumption 4 %.

to sum up

In general, I think young people with insufficient budgets want to experience a 5G mobile phone. Realme V13 is a good choice. This mobile phone is indeed a good choice in terms of overall appearance, lightness, battery life, 5G performance, photography, games, and price. Dare to leapfrog”. I actually want to say that the first 5G mobile phone for young people, why is it XX, it can be realme.
