Structural, electrical and electrochemical properties of polyacrylonitrile-ammonium hexaflurophosphate polymer electrolyte system

---

Abstract:
Polyacrylonitrile (PAN) based polymer electrolyte membranes complexedwith Ammoniumhexafluorophosphate (NH4PF6) with different molar concentration are prepared by solution casting method. Increase in the amorphous nature by the addition of Ammonium salt and the formation of polymersalt complex are confirmed by X ray diffraction studies and infrared spectroscopy respectively. The glass transition temperature is measured for all membranes and it showed a lowest value for the PAN complexed with 20 mol% of NH4PF6. Electrical properties are studied by AC impedance spectroscopy.
An ionic conductivity of the order of 10−3 Scm−1 is obtained for the 80 PAN / 20 NH4PF6 polymer electrolyte. Conductivity, dielectric and modulus spectra from the impedance data are analysed to understand the ionic transport mechanism. Transference number measurement is done to study the
ionic contribution to the charge transport. A proton battery with the configuration, Zn+ ZnSO4. 7H2O /80 PAN / 20 NH4PF6 / PbO2 +V2O5 has been constructed and its discharge characteristics are studied
