PURPOSE:To improve film strength, ion conductivity, adhesion to an electrode, etc., of a macromolecule solid electrolyte by including specified polymer, polyetyleneglycol of low molecular weight, whose both ends are methyletherified and alkalimetal salt or ammonium salt into mesh molecule of polyetyleneglycol- diacrylate polymer. CONSTITUTION:Included into mesh molecule of polyetyleneglycol-diacrylate polymer are copolymer of the compound expressed by the formula I and that by II and/or III, polyetyleneglycol of low molecular weight, whose both ends are methyletherified and alkalimetal salt or ammonium salt. In the formula I, R1 denotes the alkyl group of hydrogen or carbon whose numer is 1 to 5, R2 the alkyl group of carbon whose numer is 1 to 5 and (m) an integer of 2<=M<=30. R3 and R4 denote the alkyl group of carbon whose numer is 1 to 3 in the formulas II and III, respectively. A reinforced macromolecule solid electrolyte film is thus obtained, whose film formation and ion conductivity are improved and preferable adhesion to an electrode whose conductivity is 10<-5> to 10<-3>S/cm in a room temperature. |
