Lithium ion conducting polymer electrolytes based on triblock polymer poly(vinylidene chloride-co-acrylonitrile- co-methyl methacrylate) (or) P(VdCl-co-AN-co-MMA)-LiClO4 with tetrahydrofuran (THF) as solvent have been prepared by solution casting technique. Electrochemical impedance analysis of the polymer membranes reveals that the ionic conductivity of the polymer electrolyte increases with increase of LiClO4salt composition and the highest ionic conductivity of 1.9x10-3Scm-1 is observed for 40 wt% P(VdCl-co-AN-co-MMA)/60 wt% LiClO4 at room temperature. Alithium ion coin cell has been fabricated with a configuration of Graphite||40m%P(VdCl-co-AN-co-MMA)/60 m% LiClO4||LiFePO4and a maximum cell potential of 3.15V is observed which affirms applicability of membrane for solid state lithium ion batteries.
