With the rapid development of the lithium-ion battery (LIB) industry, the inevitable generation of fluorine-containing solid waste (FCSW) during LIB production and recycling processes has drawn significant attention to the treatment and comprehensive utilization of such waste. This paper describes the sources of FCSW in the production of LIBs and the disposal of spent LIBs. Subsequently, the fundamental characteristics of FCSW were introduced, including resource properties and hazardous attributes. Furthermore, it comprehensively reviews recent technologies for treating FCSW. Finally, future research on FCSW was prospected. This paper aims to provide practical guidance for the treatment and application of FCSW in the LIB industry, help solve the problem of resource recovery in HCSW treatment, and promote the HCSW industry to achieve more efficient and sustainable development.
