Nano Aluminum Oxide for Lithium Battery Applications

1. Nano Alumina is used as an electrode coating for lithium batteries, which can effectively insulate and insulate, and improve safety performance.

2. Nano-alumina doped with aluminum into lithium cobalt oxide can form a solid solution, stabilize the crystal lattice, and improve rate performance and cycle performance.

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

4. 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 LiCoO2 and the electrolyte, and reduce electrochemical Specific capacity loss, thereby increasing the electrochemical specific capacity of LiCoO2.

5. Nano-alumina is used to modify the spinel lithium manganate material, and the battery produced has a reversible capacity of 107mAh/g. It can be cycled at 55C for 200 times and the capacity retention rate is greater than 90%.
