“…(2) Gel polymer electrolytes derived from systems like '1' as above in which neutral polymers are added to get either highly viscous or mechanically stable self-standing membranes. [22][23][24] An interesting alternative to this system has been suggested by Watanabe's group 25,26 in which in-situ polymerization of vinyl monomers is done in ionic liquid. The polymer gel systems are a viable useful compromise between very rigid polymer electrolytes and liquid electrolytes.…”

Preparation and characterization of polymer electrolyte films of PEO+10wt.% LiPF 6 +xwt.% BMIMPF 6 (1-butyl-3-methylimidazolium hexafluorophosphate) containing dopant salt lithium hexafluorophosphate (LiPF 6 ) and ionic liquid (BMIMPF 6 ) having common anion PF -6 are reported. The ionic conductivity of the polymer electrolyte films has been found to increase with increasing concentration of BMIMPF 6 in PEO+10 wt.% LiPF 6 due to the plasticization effect of ionic liquid. DSC and XRD results show that the crystallinity of polymer electrolyte decreases with BMIMPF 6 concentration which, in turn, is responsible for the increase in ionic conductivity. FTIR spectroscopic study shows the complexation of salt and/or ionic liquid cations with the polymer backbone.

“…Ionic liquids (ILs), i.e., molten salts at temperatures approaching room conditions, are of great actual interest for their unique characteristics, which include: (1) a liquid state over a wide temperature range, which opens a series of new applications; (2) nonvolatility, which assures thermal stability and nonflammability; (3) high ion content, which results in high ionic conductivity; and (4) great chemical and electrochemical stability [1][2][3]. The most common ILs are composed of organic ions, which undergo almost unlimited structural variations because of the easy preparation of a large variety of their components.…”

This paper reviews the various classes of ionic liquids (ILs) in view of their established and expected applications in advanced electrochemical devices, such as lithium batteries, fuel cells, and supercapacitors. In this respect, particular attention is devoted to aprotic and protic ILs, with a related discussion in terms of their thermal and transport properties. In addition, the role in the electrochemical technology of a new class of ILs having cation and anion tethered in an intramolecular form is stressed. Due to their emerging importance, IL-based polymers are finally reported and discussed. A conclusion, where the expected evolution of the ILs research and development is evaluated, is also included.

“…However, when the concentration of the hydrophilic ions in W is comparable to, or lower than, the solubility of the RTIL in W, this may not be the case. In the present work, we studied the variation of the phase-boundary potential when 10 Reagent-grade KCl was used to prepare aqueous solutions of KCl. After a 0.5-dm -3 solution of 2.00 mol dm -3 KCl was prepared with MilliQ water, solutions of other concentrations were prepared as aliquots of this solution.…”

A new type of salt bridge composed of a hydrophobic room-temperature ionic liquid, recently proposed (T. T. Yoshimatsu, Bull. Chem. Soc. Jpn., 2006, 79, 1017), has been shown to be satisfactorily usable in dilute aqueous solutions of submillimolar range. A stable phase-boundary potential has been demonstrated between an ionic liquid, 1-octyl-3-methylimidazolium bis (trifluoromethylsulfonyl) ] and water is maintained constant over more than four orders of magnitude change in the concentration of an aqueous electrolyte solution. The ionic-liquid salt bridge is a superior alternative to salt bridges based on equitransferent electrolytes in practical applications, particularly, the potentiometry of samples of low ionic strengths, such as potentiometric pH measurements of rainwater.
