　　Author ：Iflowpower – Portable Power Station Supplier

Under the haze of the city, the PM2.5 has repeatedly exploded the status quo, it is important to develop and popularize new energy vehicles. In the case of a large number of retired power lithium-ion batteries brought by the new energy vehicle blowout, the industry's unreasonable row.

The resource mandatory recycling industry technology innovation strategic alliance in Beijing and the fourth power lithium-ion battery recycling seminar at November 8, and the parties of the participating power lithium-ion batteries were launched. Discuss. New energy car development rapidly "new energy car development is strong, regardless of the '12th Fiveth' or '13th Fiveth', new energy cars are all critical periods of my country's transformation from the auto national country.

"Second General Manager of Beiqi New Energy said," This year, the sales volume of new energy vehicles should be 50-6 million, according to national planning, to 2020 new energy car ownership reached 5 million, is a very realistic number. "According to the global market forecast, 2030 new energy auto market will enter the mature period of the industry, and there are some countries, such as Germany, announced that the gasoline car is no longer produced after 2030. "Mercedes-Benz proposes to 25% of the production of 25% from the pure electric car, all the car companies regard new energy vehicles as huge, potential rising market.

"原 诚 寅]. The core components of the new energy vehicle are the dynamic lithium-ion batteries, the executive vice president of my country's Material Renewal Association, and Liu Qiang, Director of Resources Mandatory Recycling Industrial Technology Innovation Strategic Alliance, said that the new energy vehicle's scrap standards for the powerful lithium-ion battery is that the battery capacity is lower than that 80%, this means that 3-5 years will replace a power lithium-ion battery. 2020 pure electric passenger car and hybrid passenger car's power lithium-ion battery scrap will reach 1.

70,000 tons, and the waste-free lithium-ion battery recycling has become an industry concerned focus. The retired battery recycling potential is large in Tsinghua University professor, and Xu Shengming, vice president of Jiangxi University of Science and Technology, and the recycling market space of the power lithium-ion battery. Value is reflected in rare metals such as cobalt, nickel.

"There is only 0.02% in my country's cobalt mine, and the currently exploded amount of exploded amount is only 40,000 tons, and the recycling of cobalt is an important way. "Currently 60% -70% of cobalt is used for battery production, and my country's cobalt relies on imports, if you can effectively recover cobalt from retired batteries, it will greatly alleviate the external dependence of rare metal resources in my country.

"Cobalt is an important strategic metal element, has a wide range of applications in industries such as hardness alloy, high temperature alloy. With the development of my country's industrial, especially the manufacturing of large aircraft, the next 10-20 years, its demand will have a large increase in space. "Xu Shengming told reporters.

Goldman Sachs expects lithium carbonate demand for 160,000 tons per year, while electric vehicle penetration is increased by 1 percentage point, will bring 70,000 tons of new carbonate demand. By 2025, only the rise of the electric car market is expected to drive the entire lithium market demand to 470,000 tons. "The giant lithium carbonate gap, even if you buy Australia, Chile's lithium ore is not enough.

". Xu Shengming. Li Jinhui, Professor Tsinghua University University, Li Jinhui, Executive Director of the Asia-Pacific Regional Center of the Basel Convention also expressed the same concerns.

With the development of new energy vehicles, "It is expected that lithium cobalt support can be maintained until 2025 to 2028, and there will be no resources available in China. However, resources have not disappeared, become part of the lithium-ion battery, become other products. "Strengthening the recycling of retired batteries has become a urgency.

For this, Liu Qiang suggested that the mechanism must first be improved. This year, the Termination and Reform Commission will jointly announce the "Electric Automobile Power Battery Recycling Technology Policy", which proposes to strengthen the further guidance and norms of electric vehicle dynamic lithium-ion battery recycling work, clarify the battery recovery responsibility Main body and vital; secondly, to establish a standardized recycling channel, actively guide the powerful lithium-ion battery recycling company, strengthen the recycling and utilization of used batteries, encourage companies that develop professional companies; again, research and development of critical technology, increase the use of waste batteries Decomposition, recombination, test, life prediction, etc. According to the recycling data minister of the Automobile Technology Research Center Data Resources Center, Xu Shujie has been discussed.

At present, the Ministry of Industry and Information Technology is exploring the management method of recycling and utilization of new energy vehicles, "basically has formed a method, and now is still in internal expert research process. middle. "Actively explore the tradder, in many experts, the retired dynamic lithium-ion battery has great energy values, directly for resource recovery, not the most economical measures.

In Li Jinhui, "The power lithium-ion battery will not be dismantled into chemical substances, it is best to use the tradder, fully play its use. In the loop utilization method, use it again to play a very important use. "However, the retired battery ladder is not imagined in practical applications.

"There are differences between the retired battery monomers, especially uniformity, followed by wooden bucket theory - the shortest wooden board determines the actual capacity of the wooden barrel, the worst battery determines the performance of the entire energy storage system. "Many experts in interview have admitted to reporters. Ming Yuebin, general manager of Harbin Batre Resources Renewable Technology Co.

, Ltd., pointed out that the important issue of the ladder application is that the battery specifications are not uniform, the monomer is poor, and the management is safe, and the cost is high. In her opinion, the target market of the ladder dynamic lithium-ion battery is distributed and microgrid, FM assist service, delaying the field of transmission and distribution expansion.

According to Ming Yue Bin, the price of the ladder dynamic lithium-ion battery is 65% -85% of the price of lithium-ion batteries, and the price advantage is not obvious. The reason is that the classification technology is not mature, not perfect; the composition proportion of groups is low; the cost of safety control parts is high; the safety risk is high, the after-sales service is high; the treatment problem after the retardation of the ladder is unresolved; the market is in the wait-and-see stage, important to pilot project Mainly, not forming a large-scale market; existing business model is immature, the supporting industry chain is not formed, unable to achieve standardized industrial products supply. "The key to retiring battery steps is the battery restructuring.

Last year, we have used some in Beijing Fangshan and Yanqing's demonstration project, and the overall performance is. "Northern Transfer Microglinal Network Technology Co., Ltd.

General Engineer Kong Qi Xiang did before accepting reporters). Zhao Guangjin, deputy director of the National Power Grid Waste Resource Treatment Technology Laboratory, told reporters. ability.

"The ideal ladder utilization efficiency and cycle life require the decommissioning battery consistency, which is to rely on sorting technology, reorganization technology, balance strategy, management system, etc. "Zhao Guangjin believes that" the key indicators of the ladder use the battery are cost and safety. "The reporter learned that although the ladder use has not yet formed a large-scale market, it has attracted a lot of companies.

For example, Harbin Baturi resource renewable technology limited public only in Beijing, there are 4 positions of storage. The ladder of Beijing Soyi Electric Company should be used in the park, the valley peak in the building project. At present, the production of battery ladder is approximately several million megawatts.

According to Wei Yuyu, the general manager of Zhejiang Chaowen Chuangyuan Industrial Co., Ltd., in the ladder utilization, it will be promoted in three aspects of the realization of battery automation, retired battery multi-level utilization, and different types of batteries.

And start the platform and online operation maintenance platform, gradually expand the retired dynamic lithium-ion battery recovery network. "It should be said that the retired battery is applied in a smaller home battery car, the UPS of the substation (constant electricity system) and a short-time home energy storage system, etc. is a good choice.

"Zhao Guangjin further said. .
