American Manganese Inc. reported the successful upcycling of lithium-ion battery black mass into NMC-811 (nickel-manganese-cobalt oxide) cathode precursor, using AMY's RecycLiCo closed-loop process. These results are a continuation of earlier success where the Company upcycled the same black mass sample intoNMC-622. Lab-scale leaching tests confirmed over 99% leach extraction efficiency of lithium, nickel, manganese, and cobalt. Following the recovery of cathode precursor material (nickel, manganese, and cobalt), the RecycLiCo process separately extracts high purity lithium while regenerating process chemicals for reuse in the process. The closed-loop and value- added processing methods achieve low chemical consumption, good overall mass balance, and refined final products that are key to lithium-ion battery manufacturing. The black mass sample was sent by an electric vehicle manufacturer to confirm the viability of American Manganese's patented process to extract valuable lithium-ion battery materials. The black mass was produced by mechanical size reduction of end-of-life lithium-ion batteries, resulting in a powder substance that contains critical battery materials, including lithium, cobalt, nickel, and manganese, as well as copper, aluminum, and graphite. The solution produced after leaching the black mass is adjusted to the desired ratio of nickel, manganese, and cobalt before the direct co-precipitation of the NMC-811 cathode precursor. The number designation following NMC indicates the ratio of nickel, manganese, and cobalt contained (i.e. the NMC-811 ratio is 80% nickel, 10% manganese, and 10% cobalt). Modern electric vehicle battery packs are predominantly shifting to higher nickel-containing cathode materials and American Manganese has demonstrated this essential processing flexibility to upcycle older electric vehicle battery materials into the next generation of lithium-ion battery cathode precursor materials.
