nickel manganese cobalt battery

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 LiNixMnyCo1-x-yO2. These materials are commonly used in lithium-ion batteries for mobile devices and electric vehicles, acting as the positively charged electrode, commonly called the cathode (though when charging it is actually the anode). When a battery is charged up, the lithium in the positive electrode is depleted, so it no longer has the formula LiNixMnyCo1-x-yO2
.

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, due to metal's high cost. Furthermore, an increased nickel content provides more capacity within the stable operation window.
