Abstract

The environmentally friendly leaching technology is the core direction to recover valuable metals from spent lithium batteries (LIBs). A new photocatalytic activation combined with organic solvent leaching is developed. Under the optimal experimental conditions, the leaching efficiencies for Li, Mn, and Co are 72.43%, 92.52% and 97.93%, respectively.
