MSDS

Polycrystalline Cathode Material with High Capacity and Stability

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

Product Information | MSDS | Literature | Related Products | Technical Support

NMC631 is named after its ratio of nickel, manganese, and cobalt. Being a mid-nickel cathode material, it displays greater capacity extracted at the same potential and improved stability, compared to low-nickel NMC cathode materials.

Delivering high specific capacity, it reaches ~200 mAh/g at 0.05 C and maintains ~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
