According to the data, the sales of new energy vehicles in China reached 3.521 million in 2021, a year-on-year increase of 1.6 times, ranking first in the world for seven consecutive years. With the rapid growth of the ownership of new energy vehicles in China, the "decommissioning" of power batteries is also increasing year by year. "Recycling power batteries is of great significance for protecting the ecological environment, improving resource utilization efficiency and ensuring the healthy and sustainable development of new energy vehicle industry." On January 12, at the press conference on the development of automobile industry in 2021 held by the Ministry of industry and information technology, Wang Weiming, director of the first Department of equipment industry of the Ministry of industry and information technology, said that in recent years, the Ministry of industry and information technology, together with relevant departments, issued and implemented a series of policies and supporting measures to strengthen the traceability management of power battery life cycle. At the same time, we carried out pilot recycling of power batteries in 17 regions including Beijing, Tianjin and Hebei, deepened cross regional cooperation and industrial chain coordination, promoted the application of advanced technology and equipment such as flexible disassembly of retired batteries, and formulated and issued a number of national, industrial and group standards. According to statistics, by the end of December 2021, 173 relevant enterprises had set up 10127 recycling service outlets in 31 provinces and cities across the country, cultivated 45 echelon and recycling backbone enterprises, actively played a demonstration and leading role, and a power battery recycling system was preliminarily established. Wang Weiming pointed out that in the next step, the Ministry of industry and information technology will earnestly implement the new energy vehicle industry development plan (2021-2035), and work with relevant departments to promote the following four aspects. First, accelerate the study and formulation of the management measures for the recycling of power batteries of new energy vehicles, further clarify the specific regulatory responsibilities of relevant national and local departments, refine the regulatory requirements for all links of power battery recycling, and strengthen regulatory constraints. The second is to study and establish the linkage mechanism of management and control of power battery recycling, strengthen the supervision and management of online and offline collaborative traceability, compact the responsibilities of relevant subjects and improve the efficiency of supervision. Third, speed up the introduction of a number of national and industrial standards for power battery recycling, and pay close attention to the publicity, implementation and implementation of the standards. Strengthen the research, promotion and application of a number of key technologies such as efficient recycling, and improve the technical level of the industry. Fourth, carry out pilot acceptance of power battery recycling, select and promote a number of typical models and enterprise case experience. We will continue to implement standardized management in the industry of comprehensive utilization of waste power batteries and establish a number of echelon and recycling benchmark enterprises.
