摘要

The following work intends to show the investigation of silver salt incorporated polymer electrolyte with the addition of Titanium dioxide (TiO2) nanofiller. A traditional solution casting method has been followed to synthesize the Nanocomposite polymer electrolyte (NPE) using Poly (vinyl alcohol) (PVA) as polymer with the addition of Silver tetrafluoroborate (AgBF4) and TiO2. The NPE investigated through structural and functional analysis to confirm the complex mixture of PVA: AgBF4:TiO2. The TiO2 dispersion and the effect of Ag-ion in the NPE is examined from surface morphology of NPE and thermal stability of the material has been studied and known that the NPE can withstand around 100 °C. Further NPE’s ionic conductivity is investigated that achieved up to 1.45 × 10− 4 S.cm− 1. The dielectric analysis shows NPE’s dielectric properties and the dipole relaxation in NPE taking place in the time of 6.05 × 10− 7 s. The NPE subjected to test in a two-electrode cell where the electrodes are prepared by activated carbon (AC). The cell’s performance is studied through electrochemical impedance spectroscopy (EIS) analysis and through equivalent electrical circuit modeling (EEC). Dielectric characteristics and complex capacitance of the cell are examined to study the performance of the cell. A real-time testing of the cell has been carried out, which analyses the charging and discharging of the cell.
