Abstract

See full text

The inventions described herein provide methods and systems for recycling lithium iron phosphate batteries, including: adding an oxidizing agent to a recycling stream of lithium iron phosphate (LiFePO4) batteries to form a leach solution; filtering the leach solution to remove a residue and obtain a lithium rich solution; modifying pH of the lithium rich solution for filtering impurities and obtaining a purified Li solution; and adding a precipitant to the purified Li solution thereby precipitating a lithium compound.
