Title:
GEL ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/2022/123916
Kind Code:
A1
Abstract:
This gel electrolyte contains a liquid and a polymer obtained by polymerization of a compound having, at both ends thereof, for example, an imidazolium salt having an alkenyl group and represented by formula (1-1) and, for example, an imidazolium salt having an alkenyl group and represented by formula (2-1). In the gel electrolyte, the polymer is swelled by the liquid. The gel electrolyte exhibits proton conductivity similar to that of Nafion at a room temperature range, and exhibits proton conductivity greater than or equal to that of Nafion at a high temperature range higher than 60°C. (In the formulae, X- represents a monovalent anion, each Y- independently represents a monovalent anion, and n represents an integer of 1-20).
