Nano Al2O3 used for lithium battery diaphragm

Application Features:

1. Nano-alumina is used as a lithium battery electrode coating, which can play the role of heat insulation and insulation, and improve safety performance

2. Improve the rate performance and cycle performance.

3. Coating lithium cobalt oxide with nano-alumina can improve thermal stability, improve cycle performance and overcharge resistance, inhibit the generation of oxygen and the decomposition of LiPF6, avoid direct contact between LiCo02 and electrolyte, and reduce electrochemical The specific capacity loss, thereby improving the electrochemical specific capacity of LiCoO2.

4. The doping of aluminum ions in nano-alumina can increase the voltage of the battery, thereby improving the safety of the battery.

5. Nano-alumina is used to modify the spinel lithium manganate material, and the reversible capacity of the battery produced is large.
