“…Fumed silica belong to acidic oxides and the Lewis acid–base interactions between the surface acid sites of the filler and anions (basically, hard bases) free up the cations and permits the higher fraction of Zn 2+ to be accessible for conduction . On the other hand, the formation of space‐charge regions between the silica particles and the GPE act as a source of electric field which further persuades the movement of charged species. Thus, the transport of cations may be facilitated either through the liquid phase of the GPEs or through the space‐charge double layer leading to higher ionic conductivity.…”

“…Thus, the transport of cations may be facilitated either through the liquid phase of the GPEs or through the space‐charge double layer leading to higher ionic conductivity. However, the enhancement of ionic conductivity is up to a certain volume fraction of the space‐charge region and as this volume fraction increases beyond a certain maximum limit (>3 wt %), the most important blocking effect of filler particles in the space‐charge region hinders the movement of cations which consequently give rise to a lower value of

t_{{Zn}^{2 +}}

values. Thus, in general, the enrichment in the

t_{{Zn}^{2 +}}

values and ionic conductivity of the gel nanocomposites is due to the augmentation in the cationic charge carriers owing to the presence of SiO 2 nanoparticles …”

Zinc ion conducting nanocomposite gel polymer electrolytes (NCGPEs) comprising of poly(vinyl chloride) (PVC)/poly(ethyl methacrylate) (PEMA) blend, zinc triflate [Zn(OTf)2] salt, 1‐ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIMTFSI) ionic liquid (IL) and fumed silica (SiO2) viz. [PVC/PEMA–Zn(OTf)2–EMIMTFSI–SiO2] exhibited the highest ionic conductivity value of 6.71 × 10−4 Scm−1 at room temperature. The ion–filler–polymer interactions and probable conformational changes observed in the structure of the gel composites due to the entrapment of IL and dispersion of nano‐sized SiO2 were confirmed from X‐ray diffraction (XRD) and Attenuated total reflection‐Fourier transform infrared (ATR‐FTIR) spectroscopy. Scanning electron microscopic (SEM) images of NCGPEs demonstrated uniform surface with abundant interconnected micropores. The cationic transport number of NCGPE samples has been found to be appreciably enhanced up to a maximum of 0.69 thus demonstrating a considerable improvement in Zn2+ ion conductivity. The NCGPE film possesses an electrochemical stability window up to 5.07 V (vs. Zn/Zn2+) and ensures feasible zinc stripping/plating in the redox process. The addition of SiO2 into the gel polymer electrolyte system has effectively reduced the glass‐transition temperature (Tg) of the NCGPE films and also accomplished improved thermal stability up to approximately 180 °C which were ascertained from Differential scanning calorimetry (DSC) and Thermogravimetric (TG) results. © 2019 Wiley Periodicals, Inc.

“…In the energy materials frame, some works are present in the literature regarding the use of ZnO hybrid materials for synthesizing ion conductive membranes as host matrices, such as PEO [216], gel-polymer electrolyte [217], and cellulose [218]. These materials could be employed as polymeric electrolytes in Li-ion batteries.…”

“…It was also found that the GPEs with ZrO 2 exhibited the best ion conductivity performance (0.46 mScm −1 at 25 • C). Sellan and Hasmi [174] found a substantial enhancement in Zn 2+ ion transport from 0.35 to 0.55 due to the dispersion of ZnO nanoparticles in a blend of 1.0 M solution of zinc triflate [Zn(Tf) 2 ] in ethylene carbonate (EC)-propylene carbonate (PC) immobilized in PVdF-HFP.…”

With the flourish of flexible and wearable electronics gadgets, the need for flexible power sources has become essential. The growth of this increasingly diverse range of devices boosted the necessity to develop materials for such flexible power sources such as secondary batteries, fuel cells, supercapacitors, sensors, dye-sensitized solar cells, etc. In that context, comprehensives studies on flexible conversion and energy storage devices have been released for other technologies such Li-ion standing out the importance of the research done lately in GPEs (gel polymer electrolytes) for energy conversion and storage. However, flexible zinc batteries have not received the attention they deserve within the flexible batteries field, which are destined to be one of the high rank players in the wearable devices future market. This review presents an extensive overview of the most notable or prominent gel polymeric materials, including biobased polymers, and zinc chemistries as well as its practical or functional implementation in flexible wearable devices. The ultimate aim is to highlight zinc-based batteries as power sources to fill a segment of the world flexible batteries future market.
