LITHIUM, NICKEL, COBALT: Tests achieve 99% leach extraction efficiency

American Manganese reports that it has successfully upcycled lithium-ion battery black mass into a nickel-manganese-cobalt oxide cathode precursor, Kallanish reports.
Lab-scale testing of the black mass samples demonstrated a 99% leach extraction efficiency of lithium, nickel, manganese and cobalt, using the company’s proprietary recycling technology, the company says.
The resulting pregnant leach solution was then adjusted to the desired ratio of nickel, manganese and cobalt before the direct co-precipitation of the NMC-622 cathode precursor. The company says the RecycLiCo NMC-6222 product shares the same high-quality technical specifications found in conventional lithium-ion battery cathode precursor materials produced from mined raw materials.
“Our continued success in upcycling EV battery production scrap and black mass broadens our business strategy and potential for strategic partners,” says president and ceo Larry Reaugh in a statement.
