PURPOSE: To increase gel strength, and also enhance an ion transmission rate by forming composition composed of specified water absorptive polyalkylaneoxide denatured material, and of non-organic oxide, irradiating electron beam on the composition, and letting the composition be impregnated with electrolyte and non-aqueous organic solvent thereafter. CONSTITUTION: Let a compound of polyalkylane oxide whose weight average molecular weight is 1000 to 1000000, with polyol and isocyanate be reacted under a presence of catalyst in a tin system and/ or in an amine system to obtain polyalkylane oxide denatured material in such a way that a ratio of the sum of end hydroxyl groups and polyol hydroxyl groups to the number of the isocynate groups of an isocynate compound is 0.5 to 2.0. Hundred parts of the aforesaid denatured material by weight is blended with 0.1 to 20 parts of non-organic oxide by weight, which is less than 10μm in grain size, so as to be formed into a composition, electron beam of 5 to 500KGy is irradiated on the aforesaid composition thereafter, the composition is then impregnated with organic solvent in a non-aqueous system whose non-organic electrolyte concentration is 10<-3> to 3mol/l at a rate of 0.001l through 20g per 1g of polyalkylane oxide. |
