“…In all clean energy devices, the solid-state batteries attract more attention due to its less toxicity, high safety, no leakage, not intercalation reaction between electrodes, lower cost, high performance etc. 1 Solid polymer electrolytes are much important for batteries due to its advantages such as no leakage, high ionic conductivity, high safety, longer life time etc. Proton conducting polymers are mostly approachable for Polymer electrolyte membrane fuel cell (PEMFC), Batteries and Supercapacitors.…”

Proton conducting solid polymer electrolytes comprising PEO: PVP blend with ammonium nitrate in different compositions are prepared by solution casting technique and they are characterized with different techniques. X-ray diffraction (XRD) shows that the prepared polymer electrolytes have amorphous nature. Fourier transform infrared(FTIR) spectroscopy confirms the functional groups present in the polymer membranes. The scanning electron microscopical(SEM) images confirm the presence of smooth surface in the polymer electrolytes. The ionic conductivity values are calculated by ac impedance technique. The maximum ionic conductivity is obtained for 12 wt% ammonium nitrate doped polymer system at ambient temperature (6.39 × 10−5 S/cm). From the transference number analysis by Wagner’s polarization technique, the type of conductivity, mobility and charge-carrier concentration are confirmed. Electrochemical performance is also investigated using cyclic voltammetry (CV) studies.

“…Preparation of composite electrolytes: The entire polymer electrolytes were prepared by conventional solution casting method. The ratio of PVA and cellulose acetate in this study was used as reported in our previous work [5]. The different mol contents of NH 4 CF 3 SO 3 (AT) salt with the optimized polymer blend were dissolved in DMSO and magnetically stirred to get the homogenous solution.…”

“…Over the past few years, many polymer blends with different lithium and ammonium salts have been reported as a potential polymer electrolyte material for solid state batteries and other electrochemical devices [1][2][3]. In the preparation of proton exchange membrane materials, different polymers like SPEEK, PVdF, PMMA, PVA, cellulose acetate, PEO, PANI and nano wires were used [4,5]. Among those, poly(vinyl alcohol) has been widely used because of its potential property to form good miscible blends.…”

In the present study, polymer electrolyte with poly(vinyl alcohol) (PVA) blended with cellulose acetate (CA) was chosen to prepare composite electrolyte using ammonium triflate salt and nano sized alumina (Al2O3- < 50 nm) by the solution casting method. The as prepared samples were characterized by X-ray diffraction, FT-IR, differential scanning calorimetry and AC impedance spectra. The loss tangent and dielectric studies were carried out for all the prepared samples using AC impedance analysis. Activation energy with regression values and relaxation time were calculated and found to be low for the highest conducting membranes. The presence of 0.1 mol content of nano alumina has enhanced the ionic conductivity significantly to the value of 2.012 × 10-3 S/cm from that of the filler-free electrolyte (2.93 × 10-4 S/cm). Ionic transference number was calculated by electrostatic polarization method and it was found to be 0.9684, which shows the conducting species were ions. A proton battery fabricated using the configuration Zn+ZnSO4. H2O || PVA-CA-0.5 mol NH4CF3SO3-0.1 mol Al2O3 || PbO2 + V2O5 produced a steady state open circuit voltage of 1.39 V, which proves the prepared composite electrolyte is suitable solid electrolyte for electrochemical devices.
