The rapid development of the new energy industry drives the rapid growth of the lithium battery industry.As the power battery type with the highest market share,lithium-ion batteries have been widely used in various industries,How-ever,with the decline of battery performance,they will face a huge problem of recycling and processing waste batteries within the foreseeable recycling cycle.The common types and structures of lithium ion batteries were briefly described,and different recycling methods for waste lithium-ion batteries were introduced.According to the relevant research status at home and abroad,the pretreatment process of waste lithium-ion batteries and the recovery and treatment technology of elec-trolytes were elaborated,the research progress of pretreatment and electrolyte recovery treatment technology was summa-rized,the applicability and characteristics of different methods were discussed,and the prospects and development direc-tions of the waste lithium-ion battery recovery industry were provided.
