An effort has been made to synthesize PVA based gel polymer electrolyte films by means of solutioncasting technique doped with silver ion in different concentration of polymer and salt (80:20, 70:30and 60:40 wt.%). The resulting PVA and CH3COOAg gel polymer electrolyte (GPE) material came tobe analyzed through various characterization methods for instance XRD, FTIR and UV-Visspectrophotometry. The analysis of FTIR and XRD confirmed the polymer and salt complexation.The ionic conductivity for prepared GPE was evaluated by means of AC impedance studies at roomtemperature. The highest value of ionic conductivity found for PVA: CH3COOAg (30 wt.%) systemwas found to be 1.422 × 10-5 S cm-1. The optical and cyclic voltammetric analysis have been examinedand excellent cyclic, reversible performance was observed for the electrolyte PVA:CH3COOAg (70:30wt.%) up to 10 cycles.
