Title:
POLYMER MEMBRANE AS WELL AS PREPARATION METHOD THEREFOR, AND COMPOSITE CURRENT COLLECTOR
Document Type and Number:
WIPO Patent Application WO/2024/036936
Kind Code:
A1
Abstract:
Disclosed in the present invention are a polymer membrane as well as a preparation method therefor, and a composite current collector. The preparation process of the polymer membrane comprises soaking, cleaning, heat treatment and so on, and specifically, a cross-linking agent is used to carry out cross-linking treatment on a high-molecular polymer membrane, so as to improve the tensile strength and the heat resistance of the polymer membrane. The composite current collector can be prepared by using the polymer membrane as a base material, such that the membrane breakage rate and the heat shrinkage rate of the composite current collector are greatly reduced, thus significantly improving the tensile strength.
