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 x Mn y Co 1-x-y O 2. These materials are commonly used in lithium-ion batteries for mobile devices and electric vehicles, acting as the positively charged cathode.
Fully reduced lithium cobalt oxide can be prepared by heating a stoichiometric mixture of lithium carbonate Li 2 CO 3 and cobalt(II,III) oxide Co 3 O 4 or metallic cobalt at 600–800 °C, then annealing the product at 900 °C for many hours, all under an oxygen atmosphere.

It is estimated that the NCA battery pack in a Tesla Model 3 contains between 4.5 and 9.5 kg of cobalt and 11.6 kg of lithium. [4] Lithium nickel oxide LiNiO 2, which is closely related to NCA, or nickel(IV) oxide NiO 2 itself, cannot yet be used as a battery material because it is mechanically unstable, shows a rapid loss of capacity and has ...
Nickel forms a series of mixed oxide compounds which are commonly called nickelates. A nickelate is an anion containing nickel or a salt containing a nickelate anion, or a double compound containing nickel bound to oxygen and other elements. Nickel can be in different or even mixed oxidation states, ranging from +1, +2, +3 to +4.

In addition to a lower (than cobalt) cost, nickel-oxide based materials benefit from the two-electron redox chemistry of Ni: in layered oxides comprising nickel (such as nickel-cobalt-manganese NCM and nickel-cobalt-aluminium oxides NCA), Ni cycles between the oxidation states +2 and +4 (in one step between +3.5 and +4.3 V), [82] [75] cobalt ...

Three types of batteries dominate the electric vehicle market. They are usually defined by the cathode material they contain: nickel-cobalt-manganese oxides (NMC), nickel-cobalt-aluminum oxide (NCA), and lithium iron phosphate (LFP). [3] LFP has become widely used in China in the 202s, while in most other countries NMC and NCA are currently ...
