Document Type and Number:
WIPO Patent Application WO/2024/099164
Kind Code:
A1
Abstract:
The present invention relates to the field of composite separators, in particular to a non-woven composite separator for a supercapacitor, and a preparation method therefor and the use thereof. The non-woven composite separator has a structure at least comprising: a base film, ceramic particle layers and bonding layers, wherein the pore diameter of the base film is 0.1-10 μm; the thickness of the base film is 10-40 μm; and the porosity of the base film is 50-80%. The non-woven composite separator for a supercapacitor provided in the present invention has excellent air permeability and puncture strength, also has good bonding performance when bonded with an electrode sheet such as a capacitor, is suitable for promotion in the field of composite separators for batteries, and has wide development prospects.
