The NC5 battery is the base model battery and has the lowest energy density. It is made with lithium iron phosphate (LFP) Chemistry. The NC20 battery has higher energy density and is made with nickel manganese cobalt (NMC) chemistry. The NC30 battery also has higher energy density and is made with NMC chemistry, but it also uses silicon. The NC50 battery is the highest energy density battery and is made with NMC chemistry and silicon. Tesla plans to use the NC5 battery in the base model versions of its cars, such as the Cybertruck and Model 3.
