2025 power battery annual report waste will up to 350,000 tons, battery treatment technology and supervision are still to be improved

In recent years, the development of new energy industry has been steadily increasing. According to the data of China Automobile Association, from January to April, the production and sales of new energy vehicles completed 232,000 and 225,000 respectively, up 142.4% and 149.2% respectively.

Behind the gradual expansion of the new energy vehicle system, the demand for recycling and recycling of power batteries has also increased. According to the prediction of China Automotive Technology and Research Center, combined with the vehicle retirement years, power battery life and other factors, from 2018 to 2020, the country's cumulative waste battery will reach 120,000-200,000 tons; by 2025, the annual report of power battery waste or up to 35 Ten thousand tons. In this regard, BAIC has said that after the power battery is decommissioned, if it is improperly disposed, it may cause environmental pollution. Therefore, it is very important to promote the recycling and resource treatment of new energy vehicle power batteries and establish a sound automobile recycling economy system.

Battery recycling enters "cooperative warfare" 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 Management of the Recycling and Utilization of New Energy Vehicles' power battery", stressing the implementation of production. The responsibility extension system requires the automobile production enterprise to bear the main responsibility for the recovery of the power battery. The measure will be implemented from August 1 this year. In the face of the upcoming interim measures for management, car companies began to lay out the battery recycling business. Among them, some car companies choose to cooperate with other companies to jointly promote the recycling of domestic power batteries and other related matters.

On January 4 this year, 16 vehicle and battery companies, including Changan, BYD and Yinlong New Energy, reached cooperation with China Railway Tower, a major power battery recycling company, to solve the problem of recycling and recycling of decommissioned power batteries. In March of this year, SAIC and Ningde Times signed a memorandum of understanding on strategic cooperation, and plans to further deepen cooperation and explore ways to jointly promote the recycling of new energy vehicles. This is also the second "marriage" between SAIC and the Ningde era following the announcement of the establishment of the battery joint venture in 2017.

In addition, the Beijing auto group company Beijing BAIC Penglong automobile service trade Co., Ltd., has and GEM Co., Ltd signed the "about retired power battery recycling in areas such as strategic cooperation framework agreement, the construction of new energy vehicles, retired power battery power battery recycling system arrangement in use, the recycling of the waste batteries, retrieving and dismantling scrapped automobiles and recycling, and other areas of the circular economy to cooperate.

Battery processing technology and supervision still need to be improved

The reporter learned that since 2012, almost every year, policies and guidance including the recycling and dismantling of power batteries have been released, 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 the relevant layout. Both market size and processing technology take time to improve.

At the two sessions this year, Wenhai Li, 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, Dongshu Cui, secretary-general of the National Passenger Car Market Information Association, believes that the key technologies for the evaluation of residual value and health status of decommissioned power storage batteries are still immature, and the research and development of related technologies for cascade utilization and recycling are relatively lagging. Industry experts need to cooperate to promote technological innovation and application, and break through technical difficulties.

"Different models have different battery designs. The internal and external structural design, module connection method, and integrated form are all different. It is not possible to use the same set of disassembly pipelines for all battery packs and internal modules, which is extremely inconvenient when disassembling the battery. Therefore, most of the processes are done manually, but the skill level of the workers may affect the yield in the battery recycling process. Therefore, it is also important to take measures and methods to ensure the safety of the battery disassembly process. Dongshu Cui introduced to the reporter.
