“…The other parameters for these cells were evaluated and are listed in Table 3. The data indicate that cell parameters are better in cells with composition (80:20).The cell parameters of the present study are superior to these of Na + -based [20][21][22][23] and Ag + -based [24] cells reported in literature. Hence, these cells offer interesting alternatives for room temperature solid state batteries.…”

This paper presents results of studies on dc electrical conductivity and transference number measurements on potassium bromate (KBrO 3 ) complexed polyvinyl chloride (PVC) films prepared by solution cast technique. Temperature dependence of dc electrical conductivity and transference number data indicated the dominance of ion type charge transport in these specimens. The magnitude of conductivity increased with increase in concentration of the salt and temperature. Using this (PVC+KBrO 3 ) electrolyte, solidstate electrochemical cells were fabricated, and their discharge profiles were studied under a constant load of 100 kΩ. Several cell profiles such as open circuit voltage, short circuit current, power density, and energy density associated with these cells were evaluated and were reported. The features of complexation of the electrolytes were studied by X-ray diffraction and Fourier transform infrared spectroscopy.

Solid polymer electrolyte films based on poly (vinyl alcohol) (PVA) complexed with sodium iodide (NaI) were prepared using solution cast technique. The structural properties of pure and complexed PVA polymer electrolyte films were examined by X-ray diffraction (XRD) studies. The XRD results revealed that the amorphous domains of PVA polymer matrix was increased with the increase in NaI salt concentration. The variation of film morphology was examined by scanning electron microscopy (SEM) studies. Fourier transform infrared spectral studies for pure and complexed PVA films revealed the vibrational changes that occurred due to the effect of dopant salt in the polymer. Direct current conductivity was measured in the temperature range of 303-373 K, and the conductivity was found to increase with the increase in dopant concentration as well as temperature. Measurement of transference number was carried out to investigate the nature of charge transport in these polymer electrolyte films using Wagner's polarization technique. Transport number data showed that the charge transport in these polymer electrolyte systems was predominantly due to ions. Using these polymer electrolytes, solidstate electrochemical cells were fabricated. Various cell parameters like open-circuit voltage, short circuit current, power density, and energy density were determined.

“…The principle characteristic bands of PEO at 1146, 1283, 1344, 1461 cm -1 are observed in the FTIR spectral profile. In addition to these vibrational bands, at 2908 cm -1 it is observed and it is attributed to aliphatic C-H stretching of PVP [16]. Another band region pertaining to PVP at 1700-1612 cm -1 is observed due to the symmetric and asymmetric of C=O stretching modes of PVP.…”

Solid polymer-blended electrolyte films of polyethylene oxide (PEO) ? polyvinyl pyrrolidone (PVP)/ lithium perchlorate embedded with iron (Fe) nanofiller in different concentrations have been synthesized by a solution casting method. The semicrystalline nature of these polymer electrolyte films has been confirmed from their XRD profiles. Polymer complex formation and ion-polymer interactions are systematically studied by FTIR and laser Raman spectral analysis. Surface morphological studies are carried out from SEM analysis. Dispersed Fe nanofiller size evaluation study has been carried out using transmission electron microscopy (TEM). In order to evaluate the thermal stability, decomposition temperature, and thermogravimetric dynamics, we carried out the TG/ DTA measurement. Upon addition of Fe nanofiller to the PEO ? PVP/Li ? electrolyte system, it was found to result in the enhancement of ionic conductivity. The maximum ionic conductivity has been set up to be 1.14 9 10 -4 Scm -1 at the optimized concentration of 4 wt% Fe nanofiller-embedded PEO ? PVP/Li ? polymer electrolyte nanocomposite at an ambient temperature. PEO ? PVP/Li ? ? Fe nanofiller (4 wt%) cell exhibited better performance in terms of cell parameters. Based on the cell parameters, the 4 wt% Fe nanofiller-dispersed PEO ? PVP/Li ? polymer electrolyte system could be suggested as a perspective candidate for solid-state battery applications.
