Abstract

Global current research progress in recycling cathode materials from spent lithium iron phosphate (LFP) batteries is reported systematically,focusing on the hydrometallurgical process and the repair-regeneration process.On this basis,the problems and challenges in the development of recycling battery materials in the future are put forward in order to provide ideas for the battery recycling research in the future.
