NMC631 is a lithium nickel manganese cobalt oxide (LiNi0.6Mn0.3Co0.1O2) cathode powder from Ossila, named for its Ni:Mn:Co ratio of 6:3:1. As a mid-nickel composition, it offers higher capacity at the same potential and better stability than low-nickel NMC cathodes, making it a practical choice for high-power lithium-ion battery development.
The material reaches a specific capacity of ~200 mAh/g at 0.05 C and retains ~173 mAh/g at 1 C, showing strong rate capability. Its polycrystalline structure supports efficient Li+ diffusion and electronic transport, which helps deliver stable cycling in cells with liquid electrolytes.
The powder is grey to black, with a D50 particle size of 5.12 µm, a tap density of 2.22 g/cm3 and a specific surface area of 0.45 m2/g. It is available in 50 g, 100 g and 250 g packs.
- Preparing cathodes for high-power lithium-ion battery research and prototyping.
- Battery R&D aimed at electric vehicles, power tools and grid storage.
- Cycling and rate-capability studies in liquid electrolyte cells.
- Exploratory studies of NMC materials as electrocatalysts for the oxygen evolution reaction.
