Title:
BASE MEMBRANE OF SWELLING ADHESIVE TAPE FOR LITHIUM BATTERY AND SWELLING ADHESIVE TAPE FOR LITHIUM BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/093168
Kind Code:
A1
Abstract:
Provided in the present invention are a base membrane of a swelling adhesive tape for a lithium battery and a swelling adhesive tape for a lithium battery. The base membrane has a three-dimensional network structure, and the three-dimensional network structure is formed by crosslinking carbon-carbon saturated bonds, wherein some of the carbon atoms of the carbon-carbon saturated bonds are substituted by an ester group chain segment. The swelling adhesive tape for a lithium battery provided by the present invention comprises a base membrane and an adhesive layer composited with the base membrane, wherein the annular initial viscous force of the adhesive layer is not less than 0.1 N/25 mm. The swelling adhesive tape can be expanded at a high rate in the area in an electrolyte, can maintain a certain strength and shape in a three-dimensional direction, does not shrink at high temperatures, and can be widely applied to lithium battery production processes.
