Abstract: The recycling of lithium-ion power batteries is one of the focuses of the current energy storage industry. To understand the recycling status of lithium battery, We comprehensively analyzes the lithium-ion power battery recycling technology from application trend, global distribution areas, major domestic and foreign applicants, global and domestic key technologies and other issues. The results show that although the lithium-ion power battery recycling technology is currently the target of the global competition, especially in China, the patent applications of all enterprises are small and the technical layout is scattered. Overall, the lithium-ion battery recycling technology is still feeling its way. At the stage, the industry outlook is unknown. Therefore, it is expected to provide some reference for the future layout and development of lithium-ion power batteries recycling.

Key words: lithium ion power battery, battery recycling technology, patent analysis
