Application features:

1. Nano alumina can be used as an electrode coating for lithium batteries, effectively providing insulation and enhancing safety performance

2. Doping aluminum into lithium cobalt oxide can form a solid solution, stabilize the lattice, improve rate performance and cycling performance.

3. Coating lithium cobalt oxide with nano alumina can improve thermal stability, enhance cycling performance and overcharging resistance, inhibit oxygen generation and LiPF6 decomposition, avoid direct contact between LiCo02 and electrolyte, reduce electrochemical specific capacity loss, and thus improve 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 battery use

5. Nano alumina is applied to modify spinel lithium manganese oxide materials, resulting in a reversible capacity of 107mAh/g, 200 cycles at 55C, and a capacity retention rate of over 90%. It is superior to similar international products and is the first material in China that can be used for high-power lithium-ion batteries.
