Application features:
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 |
