Details
Electrochemical performance test data is for reference only and there may be differences in results due to different testing methods.
1. NCM materials with high maturity, polycrystalline NCM materials are relatively easy to use.
2. Due to the small particle size, it is recommended to add more conductive agents in the electrode formulation to facilitate the performance of the material at high rates.
3. Considering the application of rate type, the packing density should not be too high, it is recommended to be around ~3.2g/cc
1. Nickel cobalt manganese ternary material NCM523, with polycrystalline small particle structure, suitable for 4.2V high-power product applications, stable structure, excellent rate performance, high specific capacity, high initial efficiency, and good cycle performance.
2. Excellent processing performance, commercial batch production products, good quality and stable quality.
3. Widely used in power tools, electronic toys, and other products.
4. Convenient for pouch cells and coin cells research.

Electrochemical Performance:
First cycle efficiency and capacity test conditions: Temperature 25°C, charge at 0.1C to 4.25V, then charge with constant voltage until the current is less than 0.02C, and then discharge at 0.1C to 2.8V.
Rate performance test conditions: Temperature 25°C, charge at 0.5C to 4.25V, then charge with constant voltage until the current is less than 0.02C, and then discharge at rates of 0.1C/0.2C/0.5C/1C/2C/3C to 2.8V.
