Valuable metals have been efficiently recovered from spent lithium iron phosphate batteries by employing a process involving via iron sulfate roasting, selective leaching, and stepwise chemical precipitation. This study proposes the selective extraction of lithium from LiFePO 4 using the iron sulfate roasting-leaching method.
A selective leaching process is proposed to recover Li, Fe, and P from the cathode materials of spent lithium iron phosphate (LiFePO 4) batteries.

In recent years, the recovery of metals from spent lithium ion batteries (LIBs) has become increasingly important due to their great environmental impact and the wastage of valuable metallic resources.
This study introduces a green and sustainable recycling method that employs environmentally benign formic acid and readily available oxygen as reaction agents for selectively leaching lithium from discarded lithium iron phosphate powder. Formic acid was employed as the leaching agent, and oxygen served as the oxidizing agent.
