Polymer solid-electrolyte composition and electrochemical cell using the composition

摘要

The polymer solid-electrolyte composition according to the present invention comprises a polymer solid electrolyte selected from the group consisting of perfluorocarbon sulfonic acid, polysulfones, perfluorocarbonic acid, styrene-divinylbenzene sulfonic acid cation-exchange resins and styrene-butadiene anion-exchange resins, and 0.01-50% by weight of fine particle silica and/or fibrous silica fiber relative to the weight of the polymer solid electrolyte.
