| Popis: | In this current study, Na+ ion conducting solid blend polymer electrolytes (NCSBPEs) based on polyethylene oxide (PEO) / polyvinyl pyrrolidine (PVP) / sodium nitrate (NaNO3) with the addition of different wt.% aluminum oxide (Al2O3) as filler were prepared using solution casting technique. The prepared solid blend polymer electrolytes are subjected to X-ray diffraction (XRD), Fourier transforms infrared (FTIR), and AC-impedance techniques. The complexation has been studied using X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR) measurements. AC-impedance spectroscopy has been used to analyze the ionic conductivity of the solid blend polymer electrolytes. The higher ionic conductivity $$(\sigma )$$ ~10–7 S/cm−1 is obtained for PEO: PVP: NaNO3 film and it was enhanced to ~ 10–5 S/cm−1 with the addition of Al2O3 filler at the ambient temperature. The dielectric and tan δ values were also calculated using the impedance analysis. In LSV (linear sweep voltammetry) studies, a broad electrochemical stability window was observed for polymer electrolytes besides CV (cyclic voltammetry) studies confirm the electrochemical behavior of the electrolytes. |
