Boehmite coating

Mar 10, 2021

Application advantages of boehmite coating in lithium battery separator:

1. Plate structure, there are gaps behind the coating, which does not affect the penetration of lithium ions and the permeability of the diaphragm.

2. Boehmite coating has excellent insulation, expands when the battery is working, and effectively blocks the current.

3. Boehmite coating has sufficient chemical and electrochemical stability and will not be corroded by electrolyte.

4. The particle size is small and the particles are uniform, which can effectively reduce the thickness of the coating and ensure the uniformity of the thickness.

5. Excellent heat resistance, effectively improving the thermal stability of the separator when the lithium battery is working and exothermic.

6. Low hardness, reduce the wear of the coating material on the machine.
