Today most electric cars are powered by batteries with NCM cathodes, whose raw materials besides lithium include nickel, cobalt and manganese.
As you probably already know, for the last few years the goal has been to reduce the use of cobalt, which is rare and expensive. Nickel is being used to replace cobalt allowing more energy-dense and cheaper batteries.
NCM 111: cathode with a Ni:Co:Mn composition ratio of 1:1:1 NCM 424: cathode with a Ni:Co:Mn composition ratio of 4:2:4 NCM 523: cathode with a Ni:Co:Mn composition ratio of 5:2:3 NCM 622: cathode with a Ni:Co:Mn composition ratio of 6:2:2 NCM 712: cathode with a Ni:Co:Mn composition ratio of 7:1:2 NCM 811: cathode with a Ni:Co:Mn composition ratio of 8:1:1 However, the next important phase in the development of NCM batteries is to replace nickel with much more abundant and cheaper manganese.
