摘要

The following work explains the electrical & electrochemical analysis of silver ion conducting polymer electrolyte using two different polymers blended together. The material synthesized through traditional solution casting technique. To synthesize the blend polymer electrolyte, Poly (vinyl alcohol) (PVA) & Poly (vinyl pyrrolidone) (PVP) were used and Silver tetrafluoroborate (AgBF4) used as salt. To confirm the polymer & salt’s complexed form the structural and functional analysis of the material were examined. The morphological and thermal analysis of the material were studied to know about the material’s surface and its thermal stability. The morphological analysis explains the complexed form of polymer and salt and the thermal analysis explains the material’s thermal degradation, which is around 50% of weight loss. Electrochemical Impedance Spectroscopy (EIS) was studied for analyzing its ionic conductivity, which achieves the ionic conductivity up to 1.089 × 10− 6 S.cm− 1 and dielectric characteristics of the material were analysed, which analyses the material’s charge storage ability and dipole relaxation process, where the material has the dipole relaxation time of 5.03 × 10− 5 s. Electrochemical characteristics like Linear sweep voltammetry (LSV) and Cyclic Voltammetry (CV) were studied. The LSV analysis shows the material’s electrochemical stability which is up to 1.3 V. CV studied for the cell AC/PPA82/AC fabricated using the synthesized material in the potential range from 0 to 1 V and its supercapacitive characteristics were analysed.
