Product introduction

The cost of boehmite coating is lower. Because boehmite has sufficient chemical and electrochemical stability, and the hardness and density are low, the coating and coating film are cut and worn less, so it can not only improve the safety of the battery And cycle performance, and can reduce costs.

Product Qualification

1) Plate-like structure, with gaps after boehmite coating, 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 the 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 improve the thermal stability of the separator when the lithium battery is working to release heat.

6) The hardness is low, reducing the wear of the coating material to the machinery.
