Abstract
The disclosure discloses a method for recycling a lithium iron phosphate waste battery, and belongs to the technical field of battery recycling. In the method for recycling the lithium iron phosphate waste battery according to the disclosure, it takes a cathode material of the waste lithium iron phosphate battery as a main body, uses a lithium source, a ferric source and a phosphorus source to supplement lithium to the cathode material for repairing, and meanwhile, rebuilds a new lithium iron phosphate coating layer containing a carbon layer cross-linked structure on a surface of the cathode material to realize regeneration of the lithium iron phosphate The disclosure also provides a regenerated lithium iron phosphate/C cathode material prepared by the recycling method.
