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. [64]
Some types of Lithium-ion batteries such as NMC contain metals such as nickel, manganese and cobalt, which are toxic and can contaminate water supplies and ecosystems if they leach out of landfills. [17] Additionally, fires in landfills or battery-recycling facilities have been attributed to inappropriate disposal of lithium-ion batteries. [18]
Hazardous items in the fire zones can include batteries, ammunition, propane tanks, pesticides, and cleaning products that can become unsafe when exposed to heat and fire. Harmful chemicals can be ...
As of 2019, NMC 532 and NMC 622 were the preferred low-cobalt types for electric vehicles, with NMC 811 and even lower cobalt ratios seeing increasing use, mitigating cobalt dependency. [ 91 ] [ 92 ] [ 87 ] However, cobalt for electric vehicles increased 81% from the first half of 2018 to 7,200 tonnes in the first half of 2019, for a battery ...
The best NMC batteries exhibit specific energy values of over 300 Wh/kg. Notably, the specific energy of Panasonic’s “2170” NCA batteries used in Tesla’s 2020 Model 3 mid-size sedan is around 260 Wh/kg, which is 70% of its "pure chemicals" value. LFP batteries also exhibit a lower operating voltage than other lithium-ion battery types.
