Nano aluminum oxide for lithium battery (Nano Al2O3)

Introduction:

Nano Al2O3 for lithium batteries is a kind of nano-powder produced by our company according to the performance of the battery and the material of the battery. It has small and uniform particle size, high purity and excellent surface performance. It is widely used in various lithium batteries, alkaline batteries, solar cells and other batteries to improve the battery performance. Energy storage performance and safety performance play an important role in energy saving and environmental protection.

Technical indicators:

Application:

1. Nano Al2O3 used as electrode coating for lithium batteries can effectively play the role of heat insulation, insulation and improve safety performance.

2. Doping Al2O3 into lithium cobalt can form solid solution, stabilize crystal lattice, improve the rate performance and cycle performance.

3. Coating nano Al2O3 on lithium cobalt oxide can improve the thermal stability, cycling performance and overcharge resistance, inhibit the formation of oxygen and the decomposition of LiPF6, avoid the direct contact between LiCo02 and electrolyte, reduce the loss of electrochemical specific capacity, thereby increasing the electrochemical specific capacity of LiCoO2.

4. The doping of aluminum ion in nano Al2O3 can increase the voltage of the battery and improve the safety of the battery.

4. Nano Al2O3 is used to modify the spinel lithium manganate material. The battery has a reversible capacity of 107 mAh/g, 55C cycle 200 times and capacity retention rate of more than 90%. It is the first material that can be used in high-power lithium-ion batteries in China.
