At present, the number of new energy vehicles in our country exceeds 2.19 million, and it is expected to reach 5 to 6.3 million in 2020. More than 200,000 tons of power batteries will be retired. The step-by-step utilization and precise disassembly and recycling of retired batteries are an urgent practical need and are also a way to promote A powerful measure for the sustainable development of the new energy automobile industry. To this end, the national key research and development plan "Solid Waste Resource Recycling" has specially deployed the research and development task of "heterogeneous compatible utilization and intelligent disassembly technology of retired power batteries". After public declaration and strict review, it was led by Tianjin Lishen Battery Co., Ltd. The applied project was finally approved. Recently, the project kick-off meeting and implementation plan demonstration meeting were held in Beijing. Representatives from departments and industries such as China Agenda 21 Management Center, Tianjin Science and Technology Bureau, China Renewable Resources Industry Technology Innovation Strategic Alliance, researcher Li Huiquan and other project implementation plan demonstration experts, and representatives from project units such as Deputy General Manager Wang Zeshen of China Electric Power Group Co., Ltd. A total of more than 50 people attended the meeting. Representatives from the 21st Century Center, a professional organization for project management, introduced the task layout and project establishment status of the special project, and put forward specific requirements for strengthening standardized management, integrated implementation, goal and problem orientation, integrity construction, and fund management during the project implementation process. Representatives from the Tianjin Municipal Science and Technology Bureau said they would continue to pay attention to and provide good services for the implementation of the project, and expected that the project results would play a role in promoting the construction of the power battery industry chain. Li Shilong, Chairman of the Renewable Resources Alliance, said that he will continue to play the role of the alliance to guide the renewable resources industry to actively build an industrial innovation chain, assist projects in completing research tasks according to quality and quantity, and provide services for the transfer, transformation, promotion and application of project technological achievements. Deputy General Manager Wang Zeshen said that he will strictly implement the responsibilities of legal entities, give full play to the role of the project leading unit, and provide support and guarantee for the integration of project organization and implementation. Researcher Xu Shengming, the project leader, made a detailed report on the project implementation plan, progress plan, organization and management, etc. The person in charge of each project made a detailed report on the project implementation plan.

　　The expert group listened carefully to the report, reviewed the implementation plan materials, fully questioned and discussed the relevant content, unanimously agreed to pass the demonstration, and put forward suggestions and opinions on the specific implementation of the project and topics. This project aims at the problems of large-scale retired power batteries such as wide variety, large performance differences, low disassembly efficiency, and poor material collection accuracy. It plans to carry out rapid grading of retired batteries, heterogeneous compatible echelon utilization, multi-dimensional identification and intelligent reprinting, Research on key technologies such as intelligent disassembly and material collection, as well as research on the ecological coupling model of the full life cycle value chain of power batteries, are expected to build a commercial operation model of the reverse supply chain of power batteries, achieve in-depth utilization and precise recycling of retired power batteries, thereby promoting The sustainable development of my country's new energy industry.
