Automobile companies are speeding up their efforts to recycle power cells

In recent years, the development of the new energy industry has been steadily improving. From January to April, 232,000 new energy vehicles were produced and sold, up 142.4 per cent and 149.2 per cent, respectively, according to the China Automobile Association.

And gradually expanding the new energy vehicle system, power battery scrap recycling and other aspects of the demand has also increased. According to the forecast of the China Automotive Technology Research Center, combined with the end-of-life life of automobiles and the life of power batteries, from 2018 to 2020, the total number of end-of-life power batteries in the country will reach 120,000 to 200,000 tons; By 2025, the annual scrap of power batteries may reach 350,000 tons. In this regard, Beiqi has stated that after the power battery is retired, if it is improperly disposed of, it is likely to cause environmental pollution. Therefore, it is very important to promote the recovery and utilization of new energy vehicle power batteries and the treatment of resources, and to establish a complete car cycle economy system.

Battery Recovery into "Combat Operation" Mode

On February 26 this year, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, the Ministry of Environmental Protection, the Ministry of Transport, the Ministry of Commerce, the General Administration of Quality Supervision, Inspection and Quarantine and the Energy Bureau jointly issued the "Interim Measures for the Recovery and Utilization of New Energy Vehicle Power Battery Management", emphasizing the implementation of the extended producer responsibility system. Automobile production enterprises are required to assume the main responsibility for power battery recovery. The measure will go into effect on August 1 this year. In the face of the interim management measures to be implemented, car companies began to layout battery recycling business. Among them, some car companies choose to cooperate with other companies to jointly promote domestic power battery recycling and reuse and other related matters.

On January 4 this year, 16 vehicle and battery companies including Chang 'an, BYD and Yinlong New Energy reached a cooperation with China Tower, a major power battery recycling company, to solve problems such as the recycling and reuse of retired power batteries. In March this year, SAIC signed a memorandum of understanding on strategic cooperation with the Ningde era. It intends to further deepen cooperation and discuss jointly promoting the recycling and reuse of new energy automotive power cells. This is also the second "marriage" between SAIC and the Ningde era after it announced the establishment of a battery joint venture company in 2017.

In addition, Beiqi Group's company Beijing Beiqi Penglong Automobile Service Trading Co., Ltd. recently signed the "Strategic Cooperation Framework Agreement on Retired Power Battery Recycling and Other Areas" with Green America Co., Ltd.. We will cooperate in the development of new energy vehicle power battery recycling systems, the use of decommissioned power battery terraces, the recycling of used batteries, and the recycling and recycling of end-of-life vehicles.

Battery treatment technology and supervision still to be improved

The Beijing News reporter learned that since 2012, almost every year, policies and guidance on power battery recycling and recycling have been issued, but related industries such as power battery recycling and reuse are still in their infancy. In addition, so far, only a few car companies have carried out the relevant layout. Both market size and processing technology require time to improve.

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 Tianjin Jinnan District People's Congress Standing Committee, pointed out that China's new energy vehicle battery recycling is facing three major problems: the scale of the scrap battery recycling market is small, the technical level is low, and the disposal of discarded batteries is not timely. . In this regard, Li Wenhai put forward three suggestions, suggesting scientific treatment of rare resources, realizing the recycling of ladders, turning waste into treasure, strengthening the management of scrap battery recycling market, and introducing preferential policies to support the recycling of new energy vehicles.

Similarly, Cuidongshu, Secretary General of the National Passenger Vehicle Market Information Association, also believes that at present, companies are still immature in assessing the residual value of decommissioned power batteries and evaluating their health status, and that the development of technologies related to echelon utilization and recycling is relatively lagging behind. It is necessary to cooperate with industry experts to promote technological innovation and application and break through technical difficulties.

"Different models have different battery designs. There are differences in internal and external structure design, module connection methods, integration forms, etc.. The same dismantling pipeline can not be used for all batteries and internal modules, resulting in battery dismantling. Very inconvenient. As a result, most processes are done manually, but the skill level of workers may affect the yield of the battery recovery process. Therefore, it is also important to adopt measures and methods to ensure the safety of battery disassembly. "Cuidongshu introduced to the Beijing News reporter.
