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.

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 ...
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 ...
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 ...

The cathode is lithium nickel cobalt manganese oxide. The use of a solid-state electrolyte reduces the contact of the μSi with the electrolyte to a flat, solid surface. This makes the spreading of Li–Si more reversible. The use of a non-metallic lithium source eliminates the high temperature that metallic lithium batteries require to charge. [1]
Li-NMC batteries using lithium nickel manganese cobalt oxides are the most common in EV. The lithium iron phosphate battery (LFP) is on the rise, reaching 41 % global market share by capacity for BEVs in 2023. [1]: 85 LFP batteries are heavier but cheaper and more sustainable.
