Title:
PROTON CONDUCTING POLYMER, SOLID ELECTROLYTE AND ELECTROCHEMICAL CELL USING THE SOLID ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/2008/053828
Kind Code:
A1
Abstract:
Disclosed is a proton conducting polymer which enables to provide a proton conducting
polymer solid electrolyte which functions under anhydrous or low humidity conditions.
The proton conducting polymer is obtained by polymerizing a polymerization
material containing an N-vinylimidazole salt obtained from N-vinylimidazole
and a Brφnsted acid, and 0.1-50% by weight of a crosslinking agent having
two or more radically polymerizable functional groups which are copolymerizable
with the N-vinylimidazole salt. Also disclosed is a proton conducting solid
electrolyte which contains the proton conducting polymer as an active ingredient.
This proton conducting solid electrolyte may be composed only of the proton
conducting polymer. As the above-described crosslinking agent, there can
be used a derivative of an acrylic acid or methacrylic acid having two or more radically
polymerizable functional groups.
