Lithium nickel cobalt manganese oxide is a major cathode material of lithium batteries, and it accounts for a major market share of cathode material of lithium batteries in the world. It combines the advantage of lithium manganese oxide, lithium nickel oxide, lithium cobalt oxide, such as capacity, high power capability, thermal stability, etc. Although the NMC battery has a lower volumetric energy density than that of the LiCoO2, the higher specific power and the long-life suit its use for power tools, electric vehicles and e-bikes.

Special Note:

  • Polycrystal structure, high capacity, high efficiency in the first cycle, good rate and cycling performance
  • Easy to process and make a slurry/electrode

Single Crystal NCM811 Cathode

Specifications

ItemValue
D10 (um)1.62
D50 (um)3.77
D90 (um)6.68
BET (m2/g)0.89
Tap Density (g/cm3)2.00
Capacity (mAh/g, 3.0~4.3V, half cell)190

Special Note:

  • High nickel cathode materials are alkaline. It should be stored in vacuum or inert gas environment to prevent reactions with the moisture and the air. An irreversible capacity loss will be found if the storage condition is not well maintained.
  • Humidity should be strictly controlled during the process of the NCA cathode, from making a slurry to drying the electrode.
  • The electrode slurry made from high-nickel cathode material is less stable than that of the conventional transition metal oxide. The electrode formula needs to be optimized.
