A green chemistry process has been developed to recycle cathode material from end-of-life lithium ion batteries. NCM111 (LiNi1/3Co1/3Mn1/3O2) was completely leached with 13 M formic acid produce two groups of salts different solubilities: sparingly soluble cobalt, manganese, and nickel (CMN) formates highly formate. During leaching, CMN formate exceeded their solubility limit in the pregnant leach solution (PLS) crystallized. Mixed were recovered by filtering PLS. Lithium evaporating filtered PLS then thermally decomposing obtained air carbonate. The purity carbonate 98.1 wt%. leaching optimized through response surface methodology experiments. minimum time required 30.8 h. Optimum conditions L/S = 2.81 mL/g (equivalent S/L 356 g/L) T 95 °C. 98% crystallized recycling is simple generates no liquid or solid waste products. only reagent acid. by-products are water vapour, which can be condensed reused, carbon dioxide gas.
