Fei Weiyang: Strengthen the research and development of advanced technologies for CR2032 battery recycling

On March 5, at the "Power CR2032 battery Recycling" decision-making consultation salon jointly sponsored by the Beijing Association for Science and Technology and the Documentation and Information Center of the Chinese Academy of Sciences, Fei Weiyang, an academician of the Chinese Academy of Sciences, said that power CR2032 battery recycling is related to environmental pollution and must be given high attention at the national level.

He said that in recent years, the key technologies of "pure electric drive" have made rapid progress, and the core technologies of electric vehicles represented by lithium-ion power batteries have made major breakthroughs, but the large-scale application of lithium batteries will also lead to a large number of retired lithium-ion batteries. Therefore, it is necessary to strengthen the research and development of advanced technologies for CR2032 battery recycling to achieve safe and efficient disassembly and integrated recycling of valuable metals to avoid secondary pollution. Sun Zhi, a researcher at the Institute of Process Engineering of the Chinese Academy of Sciences, believes that paying attention to CR2032 battery recycling is considered from the perspective of resource supply security and environmental pollution. In the future, the industrial layout should be sorted out, equipment technology and pollution prevention and control levels should be upgraded, and industrial policies should be guided to avoid overheating of local markets and cause market fluctuations.

Cui Dongshu, an expert in automobile market research at the China Automobile Dealers Association, pointed out in the report that the dominant position of strong battery companies has become a feature of the development of the new energy vehicle industry. The future development of batteries will bring huge crises and challenges to vehicle companies. Therefore, battery recycling and resource utilization should be supported and led by battery companies (rather than vehicle companies), especially leading battery companies. Yang Qingyu, senior consultant of the China Battery Alliance and senior researcher of the Beijing Green Zhihui Energy Technology Research Institute, believes that the power battery recycling industry chain includes battery recycling, cascade utilization, pretreatment, material reuse and other links. The integration of the industrial chain will be a development trend, but there are technical barriers, data barriers, and logistics barriers between various industrial links, and it is necessary to strengthen upstream and downstream cooperation. "Power lithium-ion batteries involve multiple links such as resources, technology, market, and policy. It is a systematic project. Experts have made suggestions from different angles. The results of the discussion will provide reference decision-making consultation for the municipal party committee and government through the Beijing Association for Science and Technology." Sun Xiaofeng, vice chairman of the Beijing Association for Science and Technology, said.
