Recovery of lithium and copper from anode electrode materials of spent LIBs by acidic leaching

Environ Sci Pollut Res Int. 2024 May 3. doi: 10.1007/s11356-024-33537-x. Online ahead of print.ABSTRACTIn view of the importance of environmental protection and resource recovery, recycling of spent lithium ion batteries (LIBs) is quite necessary. In the present study, lithium and copper are recycled to lithium carbonate and copper oxide from anode electrode material of the spent LIBs. The anode electrode material is firstly treated with hydrochloric acid to leach lithium (96.6%) and then with nitric acid to leach copper (97.6%). Furthermore, lithium and copper are recovered as lithium carbonate and copper oxide from their respective solutions using precipitation and calcinations. These synthesized products are further characterized using XRD, FE-SEM, and EDX analysis. Finally, a simple process is proposed for the recovery of lithium and copper from anode electrode material of spent LIBs.PMID:38700765 | DOI:10.1007/s11356-024-33537-x
