【 摘 要 】

A novel polyoxometalate gel electrolyte was synthesized by 1-(3-sulfonic group) propyl-3-methyl imidazolium (abbreviated as MIMPS) and H5SiW11VO40. The synthesized gel electrolyte was successfully characterized by infrared spectra (IR), ultraviolet spectra(UV) and X-ray diffraction (XRD). Theresults of the characterization indicate that existence of Keggin structure heteropolyanion in the tungstovanadosilicate-based ionic liquid gel. The change from crystal to amorphous was observed in the XRD patterns, before and after the cation (MIMPS) added.
