Abstract:

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,However,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 electrolytes were elaborated,the research progress of pretreatment and electrolyte recovery treatment technology was summarized,the applicability and characteristics of different methods were discussed,and the prospects and development directions of the waste lithium-ion battery recovery industry were provided.

Key words: lithium-ion batteries, pretreatment, electrolyte, recycling
