ABSTRACT:
An object of the present invention is to provide a low cost and highly ionic conductive solid electrolyte which is an organic-inorganic composite compound and is water-absorbing as well as water-resistive. Another object of the present invention is to provide electrochemical systems utilizing the above-mentioned electrolyte. The solid electrolyte of the present invention is a composite compound comprising tungstic and/or molybdic acid compound and polyvinylalcohol (PVA), and containing water. Tungstate and/or molybdate and other salt are neutralized by an acid in the aqueous solution dissolving PVA. Then, the water as the solvent of the aqueous solution is removed, and then the unnecessary salts are removed, thereby obtaining the composite compound.
