NMC is a ternary cathode material widely used in lithium-ion batteries, composed of nickel (Ni), manganese (Mn), and cobalt (Co) in a certain proportion. Its chemical formula is usually represented as LiNixMnyCozO₂ (where x + y + z ≈ 1), with nickel providing energy density, manganese enhancing structural stability, and cobalt improving conductivity and cycle life.
Key Features: High energy density: Compared to materials like LFP (lithium iron phosphate), NMC batteries have a higher energy storage capacity per unit mass, making them suitable for applications with high range requirements. Good cycle life: Under reasonable proportions (such as NMC 622 or 811), it is possible to balance energy density and durability. General thermal stability: High thermal management requirements, and there is a potential safety hazard in high-rate charging and discharging or high-temperature environments. Cost is greatly affected by metal prices: especially cobalt, which is expensive and has a concentrated supply chain.
