Ammonium Ceric Nitrate

Poly [vinylidene fluoride] (PVdF): Ammonium ceric nitrate ((NH4)2Ce(NO3)6) based Proton conducting solid polymer electrolytes (SPEs) are prepared by solution casting technique. Polymer electrolytes are characterized by several techniques. The Structural property of the electrolytes are confirmed by XRD. The functional groups present in polymer electrolytes are confirmed by FTIR. The conductivity of the polymer electrolytes are calculated by using AC impedance analysis. The Maximum ionic conductivity is obtained for 2wt% of ammonium ceric nitrate doped polymer electrolyte.

Poly Vinylidene Fluoride

Polymer electrolytes consisting of poly(vinylidene fluoride-co-hexafluoropropylene) in combination with lithium triflate (LiCF3SO3) salt of varying concentration have been prepared using the conventional solution casting technique in the argon atmosphere. Structural electrical characterizations of the synthesized electrolytes have been performed using various imaging and spectroscopic techniques. The DC conductivities determined by complex impedance plots reveal gradual increase with increase in salt concentration up to a particular limit and decrease subsequently. The maximum DC conductivity obtained at 300 K is 1.64 × 10−4 Scm−1 for the electrolyte with a polymer to salt weight ratio of 1:1.8. The temperature-dependent conductivity followed a mixed Arrhenius and Vogel–Tamman–Fulcher type behaviour for the polymer electrolytes. From the Summerfield master curve plot, the conductivity of the solid polymer electrolytes is found to depend not only on ion dynamics but also on the segmental mobility of the polymer chains.
