Product description, suggestions
The electrochemical performance test data are for reference only, and the results vary due to different test methods.
1. Ternary materials with high maturity, polycrystalline ternary materials are relatively simple to use
2. Due to the small particle size, it is recommended to add some conductive agents to the polar sheet formula, which is conducive to the magnification performance of the material
3. Considering the application of magnification type, the compaction density should not be too high, it is recommended that the compaction density ~3.2g/cc
