Special Note:
- High nickel cathode materials are alkaline. It should be stored in a vacuum or inert gas environment to prevent reactions with moisture and the air. An irreversible capacity loss will be found in 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.
