99.99% Lithium battery nano-alumina
Small particle size, uniform distribution, high purity and high specific surface area.
use:
It is used in various lithium batteries, alkaline batteries, solar cells, etc., to improve the energy storage performance and safety performance of the battery, and to play the role of energy saving and environmental protection.
1. Nano-alumina is used as the electrode coating of lithium battery, which can effectively play the role of heat insulation and insulation and improve safety performance.
2. Doping aluminum to lithium cobalt oxide can form a solid solution, stabilize the crystal lattice, and improve the 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 battery use.
4. Coating lithium cobalt oxide with nano-alumina can improve thermal stability, improve cycle performance and overcharge resistance, inhibit oxygen generation and decomposition of LiPF6, avoid direct contact of LiCo02 with electrolyte, and reduce electrochemistry. The specific capacity loss, thereby increasing the electrochemical specific capacity of LiCoO2.
5. Nano-alumina is applied to the modified spinel lithium manganate material, and the reversible capacity of the battery is up to 107mAh/g, and the 55C cycle is 200 times. The capacity retention rate is more than 90%, which is better than the international similar products. The first material available for high power lithium-ion batteries.
