摘要

This research aims to focus on the synthesis of MgO nanoparticles and various characterizations of Poly(ethylene oxide), Sodium acetate and MgO nanoparticles blended polymer electrolyte for energy storage devices. Solution cast method was used for the synthesis of polymer electrolyte films with different concentrations of nanoparticles. The prepared nanoparticle and prepared films were characterized for structural, electrical and thermal stability using different characterization techniques, X-ray diffraction, Fourier transformed infrared spectroscopy, Scanning electron microscopy, Transmission electron microscopy, Impedance spectroscopy and linear sweep voltammetry. Wanger polarization method was used for the measurement of ionic transport number. Due to the incorporation of nanoparticle in the matrix of host polymer electrolyte, resulted in an enhancement in ionic conductivity. The highest value of ionic conductivity is found to be 3.26 × 10− 5 S/cm at 40 wt% of nanoparticles. A laboratory scale supercapacitor has been fabricated with maximum conducting polymer electrolyte and characterized for electrical impedance spectroscopy and cycle voltammetry. At 5 mV/s scan rate, EDLC specific capacitance is found to be 31.7 F/g.
