Lithium Nickel Manganese Cobalt Oxide Powder (NMC631) CAS 346417-97-8 / 182442-95-1

NCM631 Cathode Material with High Capacity and Stability

A rich-nickel battery cathode material for high powder Li-ion batteries

Overview | Product Information | Related Products | Technical Support

NMC631 is named after the composition ratio of nickel, manganese and cobalt around 6:3:1, being in the NMC622 family. Being a nickel-rich cathode material, it displays greater capacity extracted at the same potential and improved stability, compared to low-nickel NMC cathode materials.

NMC631 delivers high specific capacity, reaching ~200 mAh/g at 0.05 C and maintaining ~173 mAh/g at 1 C, demonstrating strong rate capability. The polycrystalline structure provides efficient Li⁺ diffusion and electronic transport, enabling stable cycling and excellent performance in liquid electrolyte cells
