High purity alumina for lithium battery separator coating

    High purity alumina is used as a ceramic coating to be applied to the separator between the positive and negative electrodes of the lithium battery. 

    Characteristics Of High Purity Alumina For Lithium Battery Separator Coating :

1. Uniformity of particle size, can be well bonded to the diaphragm without blocking the diaphragm pore size.

2. The alumina has high purity, does not introduce impurities, and does not affect the internal environment of the battery.

3. The crystal structure of alumina is consistent, and the compatibility and infiltration of alumina to electrolyte.

4. Reduce the mechanical micro-short circuit in the circulation process, improve the cycle life.

5. The aluminum oxide coating can neutralize the free HF in the electrolyte and improve the acid resistance of the battery.

6. High purity alumina for lithium battery separator coating increases the tortuosity of micropores, and the self-discharge is lower than that of ordinary diaphragms.

7. High purity alumina for lithium battery separator coating has excellent high temperature resistance, and can maintain the shape of the diaphragm above 180 degrees Celsius.
