Abstract: The present disclosure relates to a method for the recovery of metals and metal alloys from waste Lithium-ion batteries. The method of the present disclosure uses a smelting process that is energy-efficient, cost-effective and requires comparatively reduced time. Further, the method of the present disclosure has a high metal extraction efficiency. Furthermore, the heat treatment of the residual particulate matter results in the formation of binary Co—Ni alloy and prevents the formation of Co—Ni—Mn ternary alloy during smelting.

Abstract: The present disclosure relates to a method for recovery of metal oxides/carbonates from assorted waste Li-ion batteries. The method uses less solvent and has a high extraction efficiency. Further, the method requires comparatively lesser extraction time to extract metals. Furthermore, the method of the present disclosure is cost-effective.
