| Abstract Scope |
India's growing emphasis on clean energy and electric mobility has significantly increased the demand for critical metals such as lithium (Li), cobalt (Co), nickel (Ni), and manganese (Mn) as essential materials/metals for the manufacturing of lithium-ion batteries (LIBs). Present paper reports a developed process flow sheet for the recovery of Li, Co, Ni, Mn, etc., metals from spent LIBs. This involves safe pretreatment process of spent LIBs, comprising discharging, crushing, and physical beneficiation (wet or dry process) to liberate black mass. This black mass is leached using suitable lixiviant to get metals in solution. The leach solution is processed to get pure solution metals using advanced separation techniques such as solvent extraction (SX) or ion exchange (IX), and final products are recovered through precipitation or electrowinning. The final products, Li, Co, Ni, and Mn salts and metals are obtained, which have satisfactory purity. |
