“…The imidazolium-based ionic liquid-functionalized ZnS nanoparticles could absorb a large amount of liquid electrolyte, provide a disordered network structure for ion conduction, and reduces the activation energy for ion conduction, thereby promoting a substantial increase in ionic conductivity. Meanwhile, the functionalized nanoparticles could fix the [TFSI]in the electrolyte to form a Li + ion migration channel, which contributed to a high Li + ion transference number (0.62) [65]. Ng et al designed a singleion conductor electrolyte composed of imidazolium-based ionic liquid-grafted poly(methylmethacrylate) (PMMA) nanoparticles, propylene carbonate (PC) and LiTFSI, which exhibited a relatively loose brush-like structure (Fig.…”

“…Cyclability nature of gel polymer electrolyte has also revealed form this CV curve. Electrochemical stability window of ≈4.2 V for the PVDF-HFP-LITFSI-EC:DMC GPE system has been reported by Bose et al [37]. Lie et al have shown the stability window of ≈4.5 V for the PVDF-HFP-EC:DEC-LiClO 4 system [38].…”

To overcome the drawbacks of organic solvent−based liquid electrolytes and a solid polymer electrolyte as a separator in lithium polymer battery, in the recent study gel polymer electrolyte (GPE) using poly(vinylidene fluoride− hexafluropropylene) (PVDF−HFP) and poly (methyl methacrylate) (PMMA) as host polymers, lithium perchlorate (LiClO 4 ) salt as conducting species and propylene carbonate (PC) and diethyl carbonate (DEC) plasticizers as an organic solvent has been prepared. The solution casting technique has been adopted to fabricate gel polymer electrolyte (GPE). The prepared GPE films were analyzed using different experimental techniques to discover the properties of GPE. The ionic conductivity of GPE films has been carried out using electrochemical impedance spectroscopic technique. The maximum ionic conductivity of 3.97E-4 S cm −1 has been obtained for GPE having 60 wt% PC:DEC. As an evidence of change in ionic conductivity, structural characterization has been analyzed using FTIR and SEM where, FTIR spectra reveal complex formation taking place between polymers, salt, and plasticizers and SEM micrograph shows a change in surface morphology with a change in plasticizers amount. Dielectric analysis has been also carried out in terms of dielectric constant (e¢) and dielectric loss (e). Cyclic voltammetry (CV) has been applied to find electrochemical stability window.

Ionic liquids are potential alternative electrolytes to the more conventional solid-state options under investigation for future energy storage solutions. This review addresses the utilization of IL electrolytes in energy storage devices, particularly pyrrolidinium-based ILs. These ILs offer favorable properties, such as high ionic conductivity and the potential for high power drain, low volatility and wide electrochemical stability windows (ESW). The cation/anion combination utilized significantly influences their physical and electrochemical properties, therefore a thorough discussion of different combinations is outlined. Compatibility with a wide array of cathode and anode materials such as LFP, V2O5, Ge and Sn is exhibited, whereby thin-films and nanostructured materials are investigated for micro energy applications. Polymer gel electrolytes suitable for layer-by-layer fabrication are discussed for the various pyrrolidinium cations, and their compatibility with electrode materials assessed. Recent advancements regarding the modification of typical cations such a 1-butyl-1-methylpyrrolidinium, to produce ether-functionalized or symmetrical cations is discussed.
