Xinhua News Agency, June 9, Miao Wei, member of the standing Committee of the National Committee of the Chinese people's political Consultative Conference and deputy director of the Economic Committee, said at the 2023 World Power Battery Congress that it is suggested to focus on the standardization of power battery specifications and sizes, recycling and the construction of a carbon footprint standard system. Consider the back-end recycling from the front-end design. Promote the revision of standards related to the design of easy recycling of power batteries in forward research and development, such as considering the recycling of power batteries from many aspects such as materials, structure and production technology. It is necessary to speed up the construction of power battery carbon footprint standard system, such as carbon footprint declaration, carbon emission grade classification, carbon emission threshold management and so on. This has become a key factor for power battery enterprises to go out and enhance the global competitiveness of the industry.
