Abstract
This invention includes a polyelectrolytic gel comprising a polymer component and a nonaqueous solvent, characterized in that the polymer component is a crosslinked polymer having nitrogen-containing cationic functional group or a mixture of a non-crosslinked polymer having nitrogen-containing cationic functional group and a crosslinked polymer free of nitrogen-containing cationic functional group, the polymer component being swollen with the nonaqueous solvent containing an electrolyte dissolved therein. The electrolytic gel of the invention is excellent in heat resistance and durability and also in electroconductivity, especially ion conductivity.
