N2 - The lithium ion conducting solid polymer electrolytes (SPE) based on PVAc-LiClO4 of various compositions were prepared by solution casting technique. Structure and surface morphology characterization were studied by X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM) measurements, respectively. Thermal and conductivity behavior of polymer-salt complexes were studied by employing differential scanning calorimetry (DSC) and ac impedance measurements, respectively. XRD and SEM analyses indicate the amorphous nature of the polymer-salt complexes. DSC measurements show decrease in Tg with the increase in LiClO4 concentrations. The bulk conductivity of the PVAc:LiClO4 polymer electrolytes was found to vary between 7.6×10-7 and 6.2×10-5 S cm-1 at 303 K with the increase in salt concentration. The temperature dependence of the polymer electrolyte complexes appear to obey Arrhenius law.
