Products Description
Electrochemical performance test data is for reference only and may vary due to different testing methods.
1. The material has high maturity and good processing properties.
2. It can be used alone or in combination to reduce costs.
3. This material has poor performance at high temperatures due to the dissolution of manganese.
4. Compression is recommended to be controlled at around 3.0g/cm3 (2.9-3.1g/cm3).
Advantage:
- Lithium manganese oxide with spinel structure has high specific capacity, high volumetric density, good cycle performance, structural stability, good safety, and low-temperature performance.
- It has excellent processing performance, commercialized mass production products, good quality, and stable performance.
- Widely used in power tools, low-speed electric vehicles, and other products.
- Convenient for research on pouch cells and coin cells.
- Due to the extensive use of low-cost manganese to replace the scarce and expensive resources of cobalt and nickel in this material, the cost of the material is the lowest.
