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.
In this study, a roasting-water leaching green process for highly selective lithium extraction from the cathode material of spent lithium iron phosphate (LiFePO 4) battery was proposed.
This paper details a sulphated roasting procedure for recycling spent LiFePO 4 (LFP) batteries. Thermal performance characterisation and thermodynamic calculation results show that NaHSO 4 ·H 2 O can promote lithium extraction from the Fe–P–O structure and convert it into a water-soluble sulphate.

The use of eco-friendly and low-consumption regeneration technology to retrieve valuable components from lithium-ion batteries (LIBs) helps in alleviating resource shortages and environmental pollution. This paper details a sulphated roasting procedure for recycling spent LiFePO 4 (LFP) batteries.
Various sodium salts were tested to screen proper salts for the reduction process, and a 400-g scale roasting-separation process has been demonstrated. Overall, the salt-assisted roasting is a promising way to recycle spent LiFePO4 batteries without using strong mineral acids and shows great potential for the industrial-scale implementation. 1.
