  Application:
  1.Electrode of lithium battery coated with Nano-alumina has good properties of heat insulation,insulation and high security.
  2.Adulterating nano aluminum in LiCoO₂ can form a solid solution, stable lattice and increase its rate characteristics and cycling performance.
  3.LiCoO₂ coated with nano alumina has good thermal stability, cycle performance and overcharge capacity.Nano alumina in LiCoO₂ can restrain oxygen production and decomposition of LiPF6, avoid LiCoO₂ contacting with electrolyte directly, reduce the loss of electrochemical rate 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 / g.And its capacity-keeping rate is 90% min which is better than the similar products in the world.Nano alumina is the first materials used in high-power Li-ion battery.
