NMC cathode

NMC is abbreviation for LiNixMnyCozO2 . The chemistry can take several forms such as NMC 111, NMC 532, NMC 622 or NMC 811. The number represents the ratio of nickel, manganese, and cobalt. Nickel contributes on taking high energy density but it has weak stability. In order to cover up the drawback, manganese and cobalt are added up due to their more stable structure.

The dominance amount of nickel in NMC 811 made its raw material becoming important commodity. It is said that nickel could be the next oil, as it is overcoming the battery’s material of an electric vehicle. LiNixMnyCozO2 is made from calcinating LiCO3 with NMC precursor, which came from nickel sulphate, cobalt sulphate, and manganese sulphate. Originally, cobalt and sulphate could be mine from saprolite or limonite ore. So, countries that own saprolite and limonite on their soil can be a major player of the battery industry.
