NMC 811 Cathode Active Material Powder (Lithium Nickel Manganese Cobalt Oxide)

NMC 811 is an advanced cathode active material developed for lithium-ion batteries, featuring a high nickel content. This specific variant of the Lithium Nickel Manganese Cobalt Oxide (NMC) family is optimized for applications that require high energy density, high capacity, and strong electrochemical performance.

Within the cathode structure, nickel contributes to increased energy density and capacity, while manganese enhances structural and thermal stability. Cobalt improves the overall stability of the cathode and supports efficient discharge performance. Thanks to its high nickel ratio and reduced manganese and cobalt content, the NMC 811 formulation is particularly preferred in energy-density-focused battery systems.

With these characteristics, NMC 811 is regarded as one of the key cathode materials for next-generation lithium-ion battery technologies.
