Co-recovery of spent LiCoO₂ and LiFePO₄ by paired electrolysis

Abstract

A paired electrolysis approach for recovering valuable components from LiCoO2 and LiFePO4 has been developed. This process renders an efficient and clean leaching process with reduced energy input and secondary waste emissions.

Recycling spent lithium-ion battery cathode: an overview

“…The synergistic recovery between different cathodes is mainly attributed to the redox reaction between the two electrodes. Based on the oxidizing properties of Co( iii ) in LiCoO 2 and the reducing properties of Fe( ii ) in LiFePO 4 , Zhao et al 306 used a process of electrolyzing S-LCO and S-LFP in low-concentration H 2 SO 4 solution to recover precious metals from S-LIBs. The recycling process is shown in Fig.…”
