Abstract
Abstract
Electrochemical analysis of Silver ion conducting Gel polymer Electrolyte (Ag-GPE) was done with Linear sweep Voltammetry (LSV) and Cyclic Voltammetry (CV). The silver ion conducting GPE was prepared by solution casting technique with PVA as polymer, AgBF4 as salt and de-ionized water as solvent. The synthesized films were-characterized using XRD and-FTIR to study the structural and functional characteristics of GPE and confirmed the complexation between polymer and salt. The optical properties of the Ag-GPE sample was studied by UV-Vis spectrophotometer. The highest ionic conductivity, 1.28 × 10− 5 Scm-1 was observed for Ag-GPE sample (60:40 wt%) by AC impedance. Dielectric studies of Ag-GPE samples were done from AC impedance data. LSV used to analyze the electrochemical working voltage of the synthesized material, which is found to be 1.1V. CV studies were done for highest ion conducting GPE (60:40 wt%) by fabricating two different cells. The first cell SS/GPE/Ag showed good stability up to 25 cycles and the second cell Ag/GPE/Zn was analysed for the re-dox reaction of the cell which shows the electrochemical behaviour of battery and confirmed that, the synthesized material can be used for energy storage applications.
