“…RTILs are made of 99.99 % ions [8] and are widely promoted as 'green solvent' which has many useful physicochemical properties such as high ionic conductivity, non-volatility, non-flammability, good chemical and electrochemical stability and negligible vapour pressure. The negligible vapour pressure improves the safety performance of the device and in turn acts as a possible replacement for volatile organic solvents [16,17]. They are basically molten salts at room temperature comprising of bulky asymmetrical cation and a weakly coordinating inorganic or organic anion finding their way in applications such as catalysis, extraction, absorption, distillation and chromatography.…”

“…The bulky nature and the two low energy confirmations of highly flexible TFSI anion of the ionic liquid tend to enhance the electrochemical stability of the polymer blend system and accelerate the dissociation of more ions [17]. These prepared gel polymer electrolyte membranes were characterized by different techniques like X-ray diffraction (XRD), attenuated total reflectance -Fourier transform infrared spectroscopy (ATR-FTIR), complex impedance spectroscopy, scanning electron microscopy (SEM) and electrochemical analysis etc.…”

Effective influences of 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide (EMIMTFSI) ionic liquid on the ion transport properties of micro-porous zinc-ion conducting poly (vinyl chloride) /poly (ethyl methacrylate) blend-based polymer electrolytes

A series of new gel polymer electrolytes (GPEs) based on different concentrations of a hydrophobic ionic liquid (IL) 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide (EMIMTFSI) entrapped in an optimized typical composition of polymer blend-salt matrix [poly(vinyl chloride) (PVC) (30 wt%) / poly(ethyl methacrylate) (PEMA) (70 wt%) : 30 wt% zinc triflate Zn(CF 3 SO 3 ) 2 ] has been prepared using facile solution casting technique. The AC impedance analysis has revealed the occurrence of the maximum ionic conductivity of 1.10 × 10 −4 Scm −1 at room temperature (301 K) exhibited by the PVC/PEMA-Zn(OTf) 2 system containing 80 wt% ionic liquid. The addition of EMIMTFSI into the optimized PVC/ PEMA-Zn(OTf) 2 system in different weight percentages enhances the number of free zinc ions thereby leading to enrichment of ionic conductivity. The structural and complexation behaviour of the as prepared polymer gel electrolytes was substantiated by subjecting these electrolyte films to X-ray diffraction (XRD) and Attenuated total reflectance -Fourier transformed infrared (ATR-FTIR) investigations. The wider electrochemical stability window~3.23 V and a reasonable cationic transference number (t Zn 2+ ) of 0.63 have been attained for the polymer gel electrolyte film containing higher loading of (80 wt%) ionic liquid. The development of the amorphous phase of these gel polymer electrolyte membranes with increasing ionic liquid content was observed from scanning electron microscopic (SEM) analysis. The results of the current work divulge the assurance of developing GPEs based on ionic liquids for prospective application in zinc battery systems.

“…Consequently, more salt molecule, which is non-conducting, reformed and redissociated simultaneously in order to establish a new chemical equilibrium as shown in Eq. (6). Therefore, the highest ionic conductivity of 2.36 × 10 −4 ± 0.01 S cm −1 was achieved at room temperature, when 40 wt.% of IL was added into the SPE complex because IL weakens the solvation of Mg 2+ ions in the mixtures [22,23].…”

“…Solid polymer electrolyte (SPE) is predicted to replace the conventional aqueous electrolyte in the future due to its excellent dimensional stability, easy handling, high flexibility, superior electrochemical stability, good safety performances, and long cycle life [1][2][3][4]. It received much attention due to its potential applications in electrochemical devices, such as electrochromic devices, energy conversion units (batteries/fuel cells), photochemical solar cells, supercapacitors, and sensors [4][5][6].…”

Biodegradable solid polymer electrolyte (SPE) is prepared by solution-casting technique using low-cost cellulose derivative, hydroxypropylmethyl cellulose (HPMC) as a host polymer. Owing to the hydrophobic nature of this polymer, it is predicted to exhibit low ionic conductivity upon addition of magnesium trifluoro methanesulfonate (MgTf 2 ) salt. Therefore, ionic liquid (IL), 1-butyl-3-methylimidazolium trifluoro methanesulfonate (BMIMTf), is added in order to enhance its ionic conductivity. Based on the findings, the ionic conductivity at room temperature and the dielectric behaviors of the SPE complex improved upon incorporation of 40 wt.% IL. On top of that, addition of IL reduces the degree of crystallinity and the glass transition temperature (T g ) of the SPE. The conductivity-temperature plot revealed that the transportation of ions in these films obey Arrhenius theory. The interaction between SPE complex, MgTf 2 salt, and BMIMTf is investigated by means of Fourier transform infrared (FTIR) spectroscopy through the change in peak intensity around 3413, 1570, and 1060 cm −1 , which are responsible for -OH stretching band, C-C and C-N bending modes of cyclic BMIM + , and C-O-C stretching band, respectively.
