Abstract
Lithium ion (Li+) conducting solid polymer electrolytes have been prepared by solution casting method. The prepared films were
characterized using different techniques. Fourier-transform infrared result revealed complexation of dopant with the polymer
through interaction of Li+ ion of LiCl with O-H and C=O group of polyvinyl alcohol (PVA). Ultraviolet-visible spectra show the
change in optical properties such as optical energy band gap and activation energy with doping level. Dielectric studies revealed
non-Debye nature of polymer electrolytes. Electrical properties revealed that the maximum dc conductivity of 2.28 × 10−4 S/cm
has been obtained for 15 wt% LiCl doped PVA at room temperature.
