摘要：

Different composition of lithium ion conducting PVA: Miff: Lithium trillate (LiCF3S03) polymer electrolytes have been prepared by solution casting technique. Dielectric and conductivity studies have been carried out for the prepared samples. The addition of salt into the polymer matrix increases the ionic conductivity of blend polymer electrolytes. The conductivity analysis reveals 80PVA: 20PVc1F: 15LiCF3S03 polymer electrolyte exhibits the maximum ionic conductivity of 2.7 x 10-3 S cm-1 at 303 K. The temperature dependence of ionic conductivity for all the composition of PVA: PVdF: LiCF3S03 polymer films obey Arrhenius relation. Low activation energy has been obtained for highest conducting sample. The dielectric spectra show absolute 0-relaxation peak. (C) 2013 Elsevier B.V. All rights reserved,
