“…Over the last few decades, several polymers of gel electrolyte based on different polymer systems, i.e. poly(vinylidene fluoride) (PVDF), poly(methyl methlacrylate) (PMMA), , polyacrylonitrile (PAN), − polyethylenimine (PEI), polyethylene oxide (PEO), − polyethylene glycol (PEG), , cellulose acetate (CA), − poly(vinyl acetate) (PVAc), − poly(vinyl alcohol) (PVA), ,− poly(butylacrylate) (PBA), ,, hydroxypropyl cellulose (HPC), , hydroxyethyl cellulose (HEC), copolymers such as poly(siloxane-co-ethylene oxide), , and polymer blends , in the presence or absence of plasticizers (Table ), have been used for gel polymer electrolyte preparations. Recent studies suggested that conjugated polymers with varying molecular weight influence the charge carrier mobility, molecular ordering and packing, physicochemical and optoelectronic parameters, film morphology, and photovoltaic performances of QDSSC and ssDSSC electrolytic systems. − For example, increasing polymer concentration with higher molecular weight in the electrolyte exhibits enhanced absorption properties and charged ion mobility, which positively influences the photovoltaic performance. − However, the solubility of the polymer in organic solvents is stereotypically lowered with increasing polymer concentration and polymer molecular weight due to agglomeration and gelation, leading to reduction of electrolyte performance. ,, Moreover, recently it also has been established that electrolyte properties also gradually decreased with increasing polymer polydispersity index (PDI) …”

In pursuit of alternative energy, many technologies have been explored over the decades by research communities. Among these, the utilization of solar radiation by solar cells has been extensively studied, especially in dye-sensitized solar cells (DSSCs). Among different DSSC electrolytes, polymer-based quasi-solid electrolytes have gained much attention, as they overcome shortcomings including limited ion movement and solvent evaporation of solid and liquid electrolytes, respectively. Moreover, in a polymerbased quasi-solid electrolyte, the porosity and amorphous nature of the electrolyte, which govern the ionic movement, are easily controllable. Electrospinning, an emerging method for fabricating controllable porous and amorphous polymer membranes, has been extensively used for the design of polymer-based quasi-solid electrolytes in recent decades. Low cost, ease of use, versatility, and great control over the morphology and physicochemical properties of the final product make electrospinning a potentially economically feasible technique for QDSSC electrolyte fabrication. In this comprehensive review, an overview of the recent inputs in the development of electrospun fiber-based quasi-electrolytes has been compiled. The performance of the electrospun fiber-based electrolytes has been critically reviewed based on numerous operational parameters as well as the physicochemical properties of the polymers. Key technical challenges and future research avenues for electrospinning-based QDSSCs are also discussed.

In this study, solid polymer electrolytes (SPEs) are based on methylcellulose (MC) used as a polymer host and sodium iodide (NaI) as a dopant. The SPE films are developed using different contents of ethyl carbonate (EC) as a plasticizer to enhance their properties via a solution casting method. The surface morphology of SPE films is shown using polarized optical microscopy (POM), which indicates the existence of amorphous patches due to the plasticizing effect of EC. The creation of a complex between MC, NaI, and EC was confirmed by Fourier transform infrared (FTIR) spectra. A tiny amount of EC applied to the MC-NaI polymer salt matrix increases the number of charge carriers and improves ionic conductivity. The ionic conductivity of the generated polymer electrolytes is examined using electrochemical impedance spectroscopy (EIS). The high-ion conducting PE of 5.06 × 10−3 S·cm−1 was found with the mixture MC + 50 wt% NaI + 10 wt% EC (room temperature). The linear speed voltammetry (LSV) test shows that the optimized polymer electrolyte can withstand decomposition up to 2.5 V. The optimized sample transmission numbers were calculated using a TNM (transference number measurement) approach, and the results show that 99% of the ions contribute to the conductivity, compared to only 1% of the electrons. A solid-state electrical double-layer capacitor (EDLC) was fabricated using the highest ion-conductive polymer electrolyte and graphene oxide (GO)-based electrodes. The galvanostatic charge-discharge (GCD) technique was performed, and the GCD graph shows the behavior of an ideal capacitor with a less Faradic process and a low ESR value. The GO-based cell’s columbic efficiency is 100%, and the system delivers the charge for a long duration. The EDLC cell demonstrates outstanding cyclability. The specific capacitance of the EDLC cell incorporated with MC + 50 wt. % NaI + 10 wt. % EC was found to be 154.66 F/g.

Zinc‐ion capacitors (ZICs) are promising next‐generation energy storage systems (ESS) owing to high safety, material abundance, environmental friendliness, and low cost; however, the energy density of ZICs must be improved to compete with lithium‐ion batteries (LIBs). Here, the study implements three strategies to enhance the electrochemical performance and manage dendritic growth on Zn anodes, including crafting a highly efficient redox electroactive niobium pyrophosphate (NbP2O7)/Ti3C2TX‐MXene binder‐free cathode, incorporating a NaClO4 additive electrolyte, and applying a protective Ti3C2TX‐MXene layer on Zn anode. The cathode facilitates rapid Zn2+ ion diffusion and a stable host structure. An electrostatic protection layer formed in additive electrolyte and MXene layers regulates the uniform distribution of the electric fields and supports the equalization of nucleation sites. These results are supported by density functional theory (DFT) calculations. The ZICs display an excellent specific capacitance (113.3 F g−1 at 1.5 A g−1) in aqueous additive electrolytes. The flexible solid‐state ZICs exhibits a volumetric capacitance of 865.05 mF cm−3, and an energy density of 0.347 mWh cm−3 at 2.29 mW cm−3 along with capacitance retention of >100% over 38 000 charge‐discharge cycles.
