Title:
GEL ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/2022/123917
Kind Code:
A1
Abstract:
This gel electrolyte contains a liquid, inorganic nanofibers, and a polymer obtained by polymerizing a compound which has an imidazolium salt having an alkenyl group represented by formula (1-1) and an imidazolium salt having an alkenyl group represented by formula (2-1) at both ends, and in which the compound is swelled by the liquid; the gel electrolyte exhibits proton conductivity equivalent to that of Nafion at room temperature, exhibits proton conductivity greater than or equal to that of Nafion at high temperatures exceeding 60°C, and has excellent strength. (In the formula, X- indicates monovalent anions, Y- represents mutually independent monovalent anions, and n represents an integer 1-20.)
