NCMA, when used in the context of batteries, stands for Nickel, Cobalt, Manganese and Aluminum battery chemistry. The NCMA battery chemistry is one predominantly used by LG Chem. By utilizing aluminum, LG Chem is able to decrease the use of cobalt, which is a rare metal mined in many areas of the world using inhumane methods.
