Abstract

The lithium ion conducting copolymer electrolytes based on poly(vinylidene chloride-co-acrylonitrile-co-methyl methacrylate) P(VdCl-co-AN-co-MMA)-lithium per chlorate (LiClO4) (P(VdCl-co-AN-co-MMA): LiClO4) and poly(vinylidene chloride-co-acrylonitrile-co-methyl methacrylate)P(VdCl-co-AN-co-MMA)-lithium per chlorate (LiClO4)-ethylene carbonate (EC) (P(VdCl-co-AN-co-MMA):LiClO4:EC) of different compositions were prepared by solution-casting technique. Structural and surface morphological characterizations were studied by X-ray diffraction analysis and scanning electron microscopy measurements, respectively. Thermal and conductivity behaviour of copolymer-salt and copolymer-salt-plasticizer complexes were studied by employing differential scanning calorimetry and AC impedance measurements, respectively. The highest bulk conductivity was found to be 1.94 × 10-4 S cm-1 at 303 K for the plasticized sample. The dielectric behaviour and relaxation parameters of the samples have been presented and discussed.
