Summary, etc. A comparison of various approaches evaluated to process spent lithium ion batteries to extract metals has been carried out. The leaching is carried out with sulphuric acid in the presence and absence of reductant, thus defining the role of reducing agent (NaHSO3 and H2O2) in assisting dissolution of all metals, especially Co and Mn. As the direct process incurs all metals in solution and employs high concentration of acid, a two-step process (acid baking and leaching) has been attempted to lower acid consumption indicating benefits in the selective dissolution of metals viz., Co and Li (in 1st stage) over other metals (Ni and Mn in 2nd stage).
