“…The rectangular-like shapes of cyclic voltammogram were obtained once the capacitance is potential independent, whereas if the capacitance relies on voltage the state of cyclic voltammogram displays an alternate profile [ 68 , 69 , 70 ]. The highest specific capacitance C s for the sample that is incorporated with 42 wt.% of glycerol was calculated based on Equation (4), and found to be 25.05 F/g, at the scan rate of 10 mV/s [ 71 ]. It is also noticeable that the specific capacitance C s values varied with changing the scan rates, as shown in Table 3 .…”

In this study, plasticized films of polyvinyl alcohol (PVA): chitosan (CS) based electrolyte impregnated with ammonium thiocyanate (NH4SCN) were successfully prepared using a solution-casting technique. The structural features of the electrolyte films were investigated through the X-ray diffraction (XRD) pattern. The enrichment of the amorphous phase with increasing glycerol concentration was confirmed by observing broad humps. The electrical impedance spectroscopy (EIS) portrays the improvement of ionic conductivity from 10−5 S/cm to 10−3 S/cm upon the addition of plasticizer. The electrolytes incorporated with 28 wt.% and 42 wt.% of glycerol were observed to be mainly ionic conductor as the ionic transference number measurement (TNM) was found to be 0.97 and 0.989, respectively. The linear sweep voltammetry (LSV) investigation indicates that the maximum conducting sample is stable up to 2 V. An electrolyte with the highest conductivity was used to make an energy storage electrical double-layer capacitor (EDLC) device. The cyclic voltammetry (CV) plot depicts no distinguishable peaks in the polarization curve, which means no redox reaction has occurred at the electrode/electrolyte interface. The fabricated EDLC displays the initial specific capacitance, equivalent series resistance, energy density, and power density of 35.5 F/g, 65 Ω, 4.9 Wh/kg, and 399 W/kg, respectively.

“…Solid-state electrolyte based SCDs have attracted great interest in recent years due to the rapidly growing demand of power for wearable electronics, portable electronics, printable electronics, microelectronics, and especially exible electronic devices. [173][174][175][176][177] The solid-state electrolytes have lot of advantages over other electrolytes such as good ionic conducting media, simple packaging, and liquid-leakage free etc. 178 The solid-state electrolytes developed for SCDs have been based on polymer electrolytes.…”

“…Moreover, around 70% of its capacitance was maintained after 1600 cycles. [ 131 ] To tackle the main drawbacks of the supercapacitors (drying and narrow electrochemical range), a new ion gel‐based in Li + and hydroquinone (HQ) containing ionogel (PVDF‐ co ‐HFP + [EMIM][TFSI]) were produced. The results indicate that an optimal HQ concentration, the device possesses a higher transmittance contrast (≈91%), high coloration efficiency (≈61.9 cm 2 C −1 ), high areal capacitance (≈13.6 mF cm −2 ), and good charging/discharging cyclic stability ( Figure ).…”

Ionic liquids (ILs) have emerged as a novel class of chemical compounds for the development of advanced (multi)functional materials with outstanding potential in applications of several areas due to their unique properties and functionalities. The combination of ILs with polymers, in a composite, allows for developing smart materials, which synergistically combine the features of specific polymers and ILs. Moreover, ILs can be extensively modified by the incorporation of functional groups with specific properties into the cation, anion, or both. Thus, it is possible to tune the IL, the polymer, or both to obtain a broad spectrum of multifunctional composites and address the specific requirements of many applications. This work focusses on advanced materials and strategies concerning ILs and polymers for the development of smart IL/polymer‐based materials for applications including responsive and sensitive sensors, actuators, environment, batteries, fuel cells, and biomedical applications.
