Application characteristics
1. Nano alumina powder is used as a coating for lithium battery electrodes, which can effectively play the role of heat insulation and insulation
2. Doping nano aluminum oxide aluminum into lithium cobalt oxide can form a solid solution, stabilize the crystal lattice, and improve the rate performance and cycle performance.
3. Coated lithium cobaltate with nano-alumina can improve thermal stability, improve cycle performance and overcharge resistance, inhibit the formation of oxygen and the decomposition of LiPF6, avoid direct contact between LiCo02 and electrolyte, and reduce electrochemistry Loss of specific capacity, thereby increasing the electrochemical specific capacity of LiCoO2.
4. The doping of aluminum ions in nano alumina can increase the battery voltage.
5. Nano-alumina is used to modify the spinel lithium manganate material to improve the cycle performance of the battery.
