Application:

1.Electrode of lithium battery coated with Nano-alumina has good property of heat insulation,insulation and high security.

2.Adulterating aluminum in LiCoO2 can form a solid solution, stabilize lattice and increase rate capability and cycling performance.

3.LiCoO2 coated with nano alumina has good thermal stability, cycle performance and overcharge alumina in LiCoO2 can restrain oxygen production and decomposition of LiPF6, avoid LiCo02 contact with electrolyte directly, reduce the loss of electrochemical specific capacity, and improve the electrochemical specific capacity of LiCoO2.

4. Improve the battery's voltage, thereby enhance the safety of battery.

5. The reversible capacity of spinel LiMn2O4 battery material improved by nano alumina is 107mAh / its capacity-keeping rate is 90% min which is better than the similar products in the alumina is the first materials used in high-power Li-ion battery.
