Abstrakt: The plasticized polymer electrolyte consisting of poly(epichlorohydrin-ethyleneoxide) [P(ECH-EO)], lithium perchlorate (LiClO) and γ-butyrolactone (γ-BL) have been prepared by simple solution casting technique. The polymer-salt-plasticizer complex has been confirmed by XRD analysis. The ionic conductivity studies have been carried out using AC impedance technique. The effect of plasticizer (γ-BL) on ionic conductivity has been discussed with respect to different temperatures. The maximum value of ionic conductivity is found to be 1.3 × 10 Scm for 70P(ECH-EO):15γ-BL:15LiClO at 303 K. The temperature dependence of the plasticized polymer electrolyte follows the Vogel-Tamman-Fulcher formalism. The activation energy is found to decrease with the increase in plasticizer.
