Abstract: The growing use of lithium iron phosphate (LiFePO4) batteries has underscored the critical need for effective recycling practices, and the challenges during recycling spend LiFePO4 is recovering valuable resources and regenerating new LiFePO4. In this research, formic acid and oxygen are used to selectively extract lithium from spend LiFePO4 and LiFePO4 is transferred to be lithium formate and iron phosphate. The lithium formate can be recovered as lithium carbonate while the iron phosphate can be used with lithium formate to regenerate new LiFePO4.
