Behind the gradually expanding new energy vehicle system, the demand for the recycling and reuse of scrap power batteries has also increased. According to the forecast of the China Automotive Technology Research Center, combined with factors such as the number of years of scrapped vehicles and the life of power batteries, from 2018 to 2020, the country’s cumulative scrapped power batteries will reach 120,000 to 200,000 tons; by 2025, the annual scrap volume of power batteries may reach 35 Million tons. In this regard, BAIC has said that after the power battery is retired, if it is not handled properly, it is likely to cause environmental pollution. Therefore, it is very important to promote the recycling and resource treatment of power batteries for new energy vehicles, and to establish a complete automobile circular economy system.

　　Battery recycling enters "cooperative war" mode

　　In addition, Beijing Beiqi Penglong Automobile Service and Trade Co., Ltd., a subsidiary of BAIC Group, recently signed the "Strategic Cooperation Framework Agreement on Recycling and Utilization of Decommissioned Power Batteries" with GEM Co., Ltd. to jointly build a new energy vehicle power battery recycling system. , Cooperate in circular economy fields such as the echelon utilization of decommissioned power batteries, the resource treatment of waste batteries, the recycling and dismantling of end-of-life vehicles, and the recycling.

　　Battery processing technology and supervision still need to be improved

　　The Beijing News reporter learned that since 2012, policies and guidelines covering the recycling and dismantling of power batteries have been issued almost every year, but related industries such as power battery recycling and reuse are still in their infancy. In addition, as of now, only a few car companies have carried out relevant layouts. Both the market size and the processing technology need time to perfect.

　　At the two sessions this year, Li Wenhai, member of the National Committee of the Chinese People’s Political Consultative Conference and deputy director of the Standing Committee of Tianjin Jinnan District People’s Congress, pointed out that my country’s new energy vehicle battery recycling is facing three major problems: the small scale of the scrap battery recycling market, the low level of technology, and the delayed disposal of scrap batteries. . In this regard, Li Wenhai put forward three suggestions, suggesting scientific treatment of rare resources, realization of cascade recycling, turning waste into treasure, strengthening the management of the scrap battery recycling market, and introducing preferential policies to support the recycling of scrap batteries for new energy vehicles.

　　Similarly, Cui Dongshu, secretary-general of the National Passenger Vehicle Market Information Joint Council, also believes that at present, enterprises are not mature enough to evaluate the residual value of retired power batteries, health status evaluation and other key technologies, and the research and development of related technologies for cascade utilization and recycling is relatively lagging. Industry experts are required to collaborate to promote technological innovation and application, and break through technical difficulties.

　　"Different models have different battery designs, with differences in internal and external structural design, module connection methods, integration forms, etc. The same set of disassembly lines cannot be used to fit all battery packs and internal modules, resulting in extremely inconvenient battery disassembly. Therefore, most processes are completed manually, but the skill level of the workers may affect the yield in the battery recycling process. Therefore, what measures and methods are adopted to ensure the safety of the battery disassembly process is also very important. "Cui Dongshu introduced to the Beijing News reporter.
