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 .
This type of battery is also referred to as a lithium-ion battery [1] and is most commonly used for electric vehicles and electronics. [1] The first type of lithium battery was created by the British chemist M. Stanley Whittingham in the early 1970s and used titanium and lithium as the
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
Noteworthy, Ni is cycled during the battery operation between oxidation states +2 and +3.5, Co- between +2 and +3, and Mn and Al remain electrochemically inactive. [3] 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]
One of the main research efforts in the field of lithium-manganese oxide electrodes for lithium-ion batteries involves developing composite electrodes using structurally integrated layered Li 2 MnO 3, layered LiMnO 2, and spinel LiMn 2 O 4, with a chemical formula of x Li 2 MnO 3 • y Li 1+a Mn 2-a O 4 • z LiMnO 2, where x+y+z=1. The ...
The lithium-ion battery was introduced in the market in 1991, is the choice in most consumer electronics, having the best energy density and a very slow loss of charge when not in use. It does have drawbacks too, particularly the risk of unexpected ignition from the heat generated by the battery. [13]

The cobalt atoms are formally in the +3 oxidation state, hence the IUPAC name lithium cobalt(III) oxide. Lithium cobalt oxide is a dark blue or bluish-gray crystalline solid, [ 4 ] and is commonly used in the positive electrodes of lithium-ion batteries .
