“…Thus, an enhancement of one order magnitude of conductivity has been achieved as a result of incorporation of ODAMMT nanofiller during this investigation. Moreover, this value of conductivity is found to be higher than that of the nanocomposite polymer electrolyte system prepared using conventional Al 2 O 3 nanofillers based on the same polymer-salt complex which showed a conductivity of 2.5 Â 10 À5 S cm À1 [21]. This is because of the very high aspect ratio of the nanoclay which provides larger surface area for the polymer to interact with the platelets of the nanoclay.…”

“…Hence, the occurrence of anodic oxidation and cathodic reduction at 1.27 and −0.22 V versus Zn/Zn 2+ suggest the feasibility of the system to be chemically reversible. Moreover, the peak currents decreases with increasing cycle numbers and this aspect may be due to the passivation phenomenon associated with the zinc metal surface .…”

Nanocomposite gel polymer electrolytes (NCGPEs) comprising of the solution of zinc trifluoromethanesulfonate [Zn(OTf)2] in 1‐ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIMTFSI) ionic liquid entrapped in poly(vinyl chloride)/poly(ethyl methacrylate) blend and dispersed with zirconia (ZrO2) nanofiller has been prepared via simple solution casting method. The free standing film of the composite gel polymer electrolyte system exhibited the maximum room temperature ionic conductivity of 3.63 × 10−4 Scm−1 at 3 wt% nanofiller concentration with the accomplishment of highest zinc ion transference number of 0.66. The interaction and complexation among various constituents of the resultant NCGPEs has been confirmed from X‐ray diffraction (XRD) and Attenuated total reflection‐Fourier transform infrared (ATR‐FTIR) spectroscopic studies. Differential scanning calorimetry (DSC) and thermogravimetric (TG) analyses further corroborates the improved thermal behavior of ZrO2 added gel polymer electrolytes as compared with that of filler‐free gel electrolytes. The porous morphology of the thin films was observed by scanning electron microscopy (SEM) whereas the electrochemical properties of the NCGPEs were studied utilizing linear sweep voltammetry (LSV) and cyclic voltammetry (CV).

Nanocomposite gel polymer electrolytes (NCGPEs) consisting of Zn(OTf)2 salt solution in 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ionic liquid (EMIMTFSI), entrapped in poly(vinyl chloride) (PVC)/poly(ethyl methacrylate) (PEMA) matrices, and dispersed with different concentrations of tin oxide (SnO2) nanofiller were prepared by simple solution casting method. The free-standing film of the composite gel polymer electrolyte (GPE) exhibited an optimum ionic conductivity value of 4.92 × 10−4 Scm−1 at ambient temperature. The gel composites developed predominant amorphous phase and porous morphologies, thus supporting the high ionic conduction as confirmed from X-ray diffraction (XRD) and scanning electron microscopic (SEM) studies. The complex formation properties of the materials were evaluated by attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy technique. The dispersion of nanofillers in GPEs improved the thermal behavior of the composite system to 185°C, which was ascertained by thermogravimetric (TG) analysis. The electrochemical stability window of approximately 4.37 V with feasible plating/stripping process of zinc metal on stainless steel electrode was analyzed by voltammetric studies and all these features suggested the possibility of exploiting NCGPE films as electrolytes in batteries.
