NMC Battery Chemistry

Nickel-manganese-cobalt cathodes, the high-energy-density chemistry used where range matters.

Definition

Nickel-Manganese-Cobalt lithium-ion battery chemistry, one of the most common types used in electric vehicles. NMC batteries offer a balance of energy density, safety, and cost, with varying ratios (e.g., NMC 811 has 80% nickel, 10% manganese, 10% cobalt).

In practice

Ratios are written as NMC 622 or NMC 811, the digits being the nickel-manganese-cobalt proportions. The industry has moved toward higher nickel to cut cobalt, which changed demand for both.
