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 .
The usable charge storage capacity of NCA is about 180 to 200 mAh/g. [1] This is well below the theoretical values; for LiNi 0.8 Co 0.15 Al 0.05 O 2 this is 279 mAh/g. [2] However, the capacity of NCA is significantly higher than that of alternative materials such as lithium cobalt oxide LiCoO 2 with 148 mAh/g, lithium iron phosphate LiFePO 4 with 165 mAh/g and NMC 333 LiNi 0.33 Mn 0.33 Co 0. ...
Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.
12.5 × 2.0 Used in keychain LED flashlights, and in some digital cameras to keep the time and date function running even when the main battery is taken out of the camera.

2 O 4 ·2 H 2 O, in the form of rod-like crystals about 8 μm long and 0.4 μm wide, with lithium hydroxide LiOH, up to 750–900 °C. [9] A third method uses lithium acetate, cobalt acetate, and citric acid in equal molar amounts, in water solution. Heating at 80 °C turns the mixture into a viscous transparent gel.
