Abstract

Abstract : Synthesis and conductive performance of two vanadium-substituted polyoxometalate acid salt gel electrolytes, [PyPS]3 H4 SiW9 V3 O40 and [PyPS]5 H2 SiW9 V3 O40, have been reported. Abstract : Two vanadium-substituted polyoxometalate acid salt gel electrolytes, [PyPS]3 H4 SiW9 V3 O40 and [PyPS]5 H2 SiW9 V3 O40, have been synthesized using a 1-(3-sulfonic group) propylpyridine (PyPS) and a Keggin vanadium-substituted heteropoly acid H7 SiW9 V3 O40 through an ionic self-assembly method, and adjusting the ratio of cation and anion. A substitution effect of the acid salt gel electrolytes has been investigated. Interestingly, when protons of the polyoxometalate acid salt gel electrolytes are substituted, both the conductivity and the phase transformation temperature increase. The fastest conductivity of these gel electrolytes was as high as 2.57 × 10 −2 S cm −1 at 110 °C.
