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.

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 ...

The cathodes of lithium-ion batteries are often made of lithiated oxides of cobalt, nickel, or manganese, that can readily and reversibly incorporate lithium ions in their molecular structure. Cobalt oxide nanomaterials, such as nanotubes , [ 1 ] offer high surface-to-volume ratio and short path lengths for lithium cation transport, leading to ...
The lithium nickel cobalt aluminium oxides (abbreviated as Li-NCA, LNCA, or NCA) are a group of mixed metal oxides. Some of them are important due to their application in lithium-ion batteries . NCAs are used as active material in the positive electrode (which is the cathode when the battery is discharged).
The materials of the stoichiometry Li 2 MO 3-LiMO 2 are similar to the lithium rich lithium nickel manganese cobalt oxide (NMC) materials but without the cation ordering. The extra lithium creates better diffusion pathways and eliminates high energy transition points in the structure that inhibit lithium diffusion.
Nickel manganese oxides, [1] or nickel manganates, are spinel structure compounds of Nickel, Manganese and Oxygen of the form: Ni (x) Mn (3-x) O (y) [2] [3] Some common forms are Ni 2 MnO 4, NiMn 2 O 4, and Ni 1.5 Mn 1.5 O 4. They are most commonly formulated for use in thin film resistors and thermistors. [4]
