- Abstract
Nanocomposite solid polymer electrolyte films were prepared by doping TiO2 nanofiller with different wt% compositions of PVP-CH3COOK by solution cast technique. Optical absorption studies were performed in the wavelength region 200-800 nm. The energy bandgap values of direct and indirect transitions have been measured and their values were found to be decreasing with increasing wt% of salt. DC ionic conductivity measurements of the prepared nanocomposite films were performed by lab made conductivity four-probe method. The maximum ionic conductivity was found to be 2.01x10-3 S/cm at 373 K of the prepared composition 60PVP:40 CH3COOK: TiO2 (1 wt %). Transference number of ions and electrons were calculated by Wagner's polarization technique. By using the prepared nanocomposite polymer films, a battery with different wt% ratios has been fabricated and the discharge performance of the cells was presented in this investigation.
