Lithium nickel manganese cobalt oxides

Lithium nickel manganese cobalt oxides (abbreviated NMC, Li-NMC, LNMC, or NCM) are mixed metal oxides of lithium, nickel, manganese and cobalt with the general formula LiNi_xMn_yCo_1-x-yO₂. These materials are commonly used in lithium-ion batteries for mobile devices and electric vehicles, acting as the positively charged cathode.

There is a particular interest in optimizing NMC for electric vehicle applications because of the material's high energy density and operating voltage. Reducing the cobalt content in NMC is also a current target, owing to ethical issues with cobalt mining and the metal's high cost. Furthermore, an increased nickel content provides more capacity within the stable operation window.
