As state⁃of⁃the⁃art batteries，lithium⁃ion batteries（LIBs） have become the most widely used batteries.China's LIBs shipments amounted to as much as 750 GW·h in 2022 and keep on a continuous growth trend.The growing use of LIBs has triggered great concern about the environmental impact and resource utilization of spent LIBs.Lithium⁃ion battery electrolyte is a key component of lithium⁃ion batteries，mainly composed of high⁃value lithium salt electrolyte and organic solvents，while the electrolyte recycling technology for decommissioned lithium⁃ion batteries is still in the developmental stage，and there is no industrialized application yet.In order to cope with the dramatic increase of decommissioned LIBs，it is of great practical significance to study green and efficient recycling technologies to realize the resource recovery of electrolyte in a safe and environmentally friendly way.Various types of technologies on lithium⁃ion battery electrolyte recycling were comprehensively overviewed and analyzed from the perspectives of principle，environmental impact，efficiency，and industrialization prospect.And the current technologies were divided into direct recycling and conversion recycling based on the recycling principle.In addition，future research directions and challenges were proposed.
