“…The dc conductivity of the prepared polymer electrolyte has been obtained by extrapolating the plateau region on the log σ axis. The calculated dc conductivity values from the conductance spectra are in good agreement with those obtained from the Cole-Cole plot 20 . Figure 2(d) shows the frequency dependent conductivity spectra of 9 mol% 2ABSA -PVP polymer electrolyte at various temperatures in the range of 33-100 °C.…”

A solid polymer electrolyte system based on polyvinyl pyrrolidone (PVP) complexed with amino benzene sulphonic acid isomers have been prepared by solution casting technique. The conductivity measurements were carried out on these films as a function of frequency at various temperatures. The complex impedance spectroscopy results reveal that the high-frequency depressed semicircle is due to the bulk effect of the material. The conductivity is enhanced to the order of 10-6 S/cm upon increase in salt concentration at room temperature. The 2 and 4-amino benzene sulphonic acid enhances the conductivity of PVP by donating its proton from the sulphonic acid group very effectively. Thus the maximum ionic conductivity (8.44x 10-6 S/cm) is obtained for 9 mol% 2-amino benzene sulphonic acid (2ABSA) complexed PVP polymer electrolyte.

“…However, at the high-frequency region, owing to the fast periodic reversal of the electric field, there are no excess ions available to diffuse in the direction of electric field and hence such a situation in turn may tend to contribute to the decrease in the observed ∊ r . 14 It is clearly seen that the maximum value of ∊ r obtained at 10 kHz increases with 5 wt% TiO 2 filler concentration and beyond which it tends to decrease.…”

New nanocomposite polymer electrolytes have been synthesized by solution casting technique with a view to investigate detailed transport characteristics of a zinc (Zn2+) ion-conducting polymer electrolyte system, namely, poly(vinilydene fluoride-co-hexafluoropropylene):zinc triflate in the ratio of 75:25 dispersed with 1, 3, 5, 7, and 10 wt% titanium dioxide (TiO2) nanofiller, respectively. The particular polymer electrolyte specimen having 5 wt% TiO2 nanofiller exhibited the maximum electrical conductivity of 3.4 × 10−4 S cm−1 at room temperature (298 K). Frequency response analysis in terms of conductivity and dielectric relaxation studies has been carried out in order to ascertain the possible movement of ions within the polymer matrix. The modulus spectra show the existence of a non-Debye type of relaxation occurring with a distribution of relaxation times. The Zn2+ ionic transport number has been determined to be approximately 0.57, thereby suggesting the predominant impact of Zn2+ ions toward the measured total electrical conductivity. Differential scanning calorimetric results have confirmed that with the loading of TiO2 nanofiller up to 5 wt%, glass transition temperature and degree of crystallinity of the polymer decrease but increase slightly beyond 5 wt% TiO2. The present X-ray diffraction analysis has revealed the occurrence of ion/filler interactions within the polymer network due to the dispersion of TiO2 nanofiller. Certain device characteristics have also been evaluated by fabricating an appropriate electrochemical cell based on Zn/manganese dioxide electrode couple as an area of application and examining relevant discharge features.

“…The Table 3 indicates that among the various concentrations of CA:NH 4 SCN polymer electrolyte the 50CA:50NH 4 SCN polymer electrolyte has highest ionic conductivity (3.31 9 10 -3 S cm -1 ) at room temperature, which also has greater conductivity than that of pure CA (1.285 9 10 -7 S cm -1 ). The higher ionic conductivity of 50CA:50NH 4 SCN may be arises due to the transition from semicrystalline phase to an amorphous phase of polymer complex and increase in charge carrier concentration [40]. The Table 3 also indicates that the ionic conductivity is increases with respect to the increase in salt concentration.…”

In this present work, the solution casting technique was utilized to develop the proton conducting solid biopolymer electrolyte by the complex formation of cellulose acetate (CA) with the ammonium thiocyanate (NH 4 SCN) salt. The crystalline nature and complex formation of CA with different concentrations of NH 4 SCN were investigated using X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopic techniques. The XRD analysis revealed that the amorphous natures of the CA complex were increased with increase of NH 4 SCN salt concentration, which leads to the higher ionic conductivity. The FTIR analysis confirmed the complex formation between CA and salt matrix. Differential scanning calorimetry (DSC) was used to predict the glass transition temperature (T g ) values, which reveals that the T g value increase with respect to the increase of NH 4 SCN concentration. The electrical conductivity was measured using AC impedance analyzer, which showed that the magnitude of ionic conductivity increases with an increase in salt concentration up to 50CA:50NH 4 SCN. The 50CA:50NH 4 SCN has maximum ionic conductivity value of 3.31 9 10 -3 S cm -1 . Transference number measurement was carried out to investigate the nature of the charge transport species in the polymer electrolyte. The proton battery was constructed with the highest conducting polymer electrolyte 50CA:50NH 4 SCN and its open circuit voltage with load were studied. Hence, the present investigation paves the way for the development of fuel cell and primary proton battery applications.
