A polymeric gel electrolyte comprising: (a) an acrylic ester polymer matrix containing structural units derived from at least one acrylic ester selected from among acrylic esters represented by the general formulae: <CHEM> (wherein, in the formula (I), R<1>, R<2> and R<2>' are identical with or different from each other and represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, R<3> represents an alkyl group having 1 to 4 carbon atoms, and n is an integer of 1 to 100; and, in the formula (II), R<4> to R<9> are identical with or different from each other and represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, and p, q and r are identical with or different from each other and are an integer of 1 to 100); (b) a nonaqueous solvent of a carbonic ester; and (c) a salt of a metal of Group Ia of the periodic table. This polymeric gel electrolyte uses an acrylic ester polymer as a polymeric matrix and contains a specified nonaqueous solvent, so that it exhibits high ionic conductivity and is electrochemically stable. Thus, the polymeric gel electrolyte can suitably be used in electrochemical devices such as a primary battery, a secondary battery, a capacitor and an electrochromic display and in medical actuators. |
