How to strengthen the research and development of advanced technology for lithium battery recycling

by:CTECHi     2021-08-10

The 'Power Lithium Battery Recycling' decision-making consultation salon co-sponsored by the Beijing Association for Science and Technology and the Documentation and Information Center of the Chinese Academy of Sciences was recently held in Beijing Greenland Center. Fei Weiyang, an academician of the Chinese Academy of Sciences, pointed out that in recent years, the key technology of 'pure electric drive' has made rapid progress. Major breakthroughs have been made in the core technology of electric vehicles represented by lithium-ion power batteries, but the large number of applications of lithium batteries will also lead to a large number of retirements. Lithium Ion Battery. Therefore, it is necessary to strengthen the research and development of advanced lithium battery recycling technologies to achieve safe and efficient dismantling and integrated recycling of valuable metals to avoid secondary pollution.

Fei Weiyang believes that the recycling of power lithium batteries is related to environmental pollution and must be paid close attention to at the national level. This event gathers the Beijing Association for Science and Technology, the Chinese Academy of Sciences Literature and Information Center, scientific researchers, industry and industry associations, and capital and industrial operators such as Greenland Group. The concerted efforts of everyone will inevitably help the healthy and rapid development of the industry.

In the report, Sun Zhi, a researcher at the Institute of Process Research, Chinese Academy of Sciences, combed and detailed lithium battery recycling technology. He also believes that paying attention to lithium battery recycling is considered from the perspective of resource supply safety and environmental pollution. In the future, the industrial layout should be sorted out, the equipment technology and pollution prevention level should be upgraded, and industrial policies should be guided to avoid overheating of the local market and causing market fluctuations.

Cui Dongshu, an automotive market research expert from 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 automobile industry. Vehicle companies bring huge crises and challenges. Therefore, battery recycling and resource utilization should be supported by battery companies (not vehicle companies), especially leading battery companies.

Yang Qingyu, senior consultant of China Battery Alliance and senior researcher of Beijing Green Smart Energy Technology Research Institute, pointed out that the power battery recycling industry chain includes battery recycling, echelon utilization, pretreatment, materials Reuse and other links, the integration of industrial chains will be a development trend, but there are technical barriers, data barriers, and logistics requirements between various industrial links, and upstream and downstream cooperation must be strengthened.

It is understood that with the rapid development of the new energy vehicle market, lithium batteries for new energy vehicles have entered a period of large-scale scrapping, which on the one hand brings about waste of resources and environmental pollution. On the other hand, many issues in various aspects, such as lithium battery recycling technology and standards, require further discussion. Sun Xiaofeng, vice chairman of the Beijing Association for Science and Technology, concluded that power lithium-ion batteries involve resources, technology, markets, policies and other links. It is a systematic project. The results of experts and scholars from different perspectives will be provided to the government through the Beijing Association for Science and Technology.
