Abstract
Li+ ion conducting polymer electrolyte films have been prepared based on Poly (Vinyl alcohol) - Poly (Vinyl pyrrolidone) blend with LiClO4 using a solution casting technique. The increase in the amorphous nature of the polymer electrolytes has been confirmed by XRD analysis. The complex formation between the polymer and the salt has been confirmed by FTIR analysis. The highest ionic conductivity has been found to be 8.64 × 10−6 Scm−1 at ambient temperature for 0.22 molecular weight percentage of LiClO4 doped Poly (Vinyl alcohol) - Poly (Vinyl pyrrolidone) blend with low activation energy (0.59 eV). The dielectric behavior has been analyzed using dielectric permittivity (ϵ′) of the samples.
