Document Type and Number:
WIPO Patent Application WO/2020/107858
Kind Code:
A1
Abstract:
A preparation method for a cross-linked polymer electrolyte, and a semisolid polymer battery and a preparation method therefor. A cyclic borate ester with two terminal groups as alkenyl groups is taken as a cross-linking agent to cause in-situ polymerization of a polymer monomer and the like on a support material, to obtain a cross-linked polymer electrolyte. The preparation method for the electrolyte is simple; the polymer electrolyte has small interface resistance and good compatibility with an electrode, and has good mechanical properties, high electrical conductivity, and a great transport number; the polymer battery assembled using the polymer electrolyte has good stability and rate performance.
