摘      要：Novel gel polymer electrolytes(GPEs)composed of polyvinyl alcohol(PVA)and sodium thiocyanate were developed via a solution casting *** ionic liquid(IL),1-ethyl-3-methyl-imidazolium tricyanomethanide([EMIM][TCM]),was doped into a polymer–salt complex system(PVA+NaSCN)to further enhance the ***-doped polymer electrolyte(ILDPE)films were characterized using X-ray diffraction(XRD),polarized optical microscopy(POM),Fourier-transform infrared(FTIR)spectroscopy,and conductivity *** was performed to check the degree of crystallinity and amorphicity of the ILDPE films,and the amorphicity of GPEs increased with the increase of the IL *** was employed to evaluate the changes in the surface morphology due to the inclusion of salt and IL in the *** compositional nature of the GPE films was examined via FTIR *** electrical and electrochemical properties were characterized by cyclic voltammetry and electrochemical impedance *** maximum conductivity for the GPE film was estimated to be 1.10×10^(-5) S/cm for 6%(mass fraction)of IL in the polymer–salt *** ionic transference number was approximately *** electrochemical double-layer capacitor(EDLC)was built from optimized GPE films and reduced graphene oxide-based *** specific capacitance calculated from the cyclic voltammograms of the EDLC cells was 3 F/g.
