Ion Conduction in Plastic Crystals

Electrochemical Reactivity in Room-Temperature Ionic Liquids

“…For any electrochemical process, the conductivity is a property of primary importance and the conductivity of the RTILs has been reviewed on several occasions, for example refs , , and . Being composed entirely of ions, RTILs are supposed to be among the most concentrated electrolytic fluids with many charge carriers per unit volume.…”

Sum Frequency Generation Studies of Ammonium and Pyrrolidinium Ionic Liquids Based on the Bis-trifluoromethanesulfonimide Anion

“…Alkylammonium cations, for instance, are sufficiently electrochemically stable to be used as supporting electrolytes, and their melting points approach room temperature as the overall size of the ammonium ion becomes large, and the asymmetry of the molecule increases. , Pyrrolidinium cations display similar characteristics and, in addition, possess higher conductivities in most of the cases . They lie conceptually between the fully 3-dimensional quaternary ammonium cations and the close-to-planar imidazolium ions; some possess larger electrochemical windows compared with the ammonium based ones, and they are able to form ionic liquids that show plastic crystal behavior. ,, Finally, both alkylammonium and alkylpyrrolidinium cations have lower costs compared with imidazolium ions…”

Structural and Electrochemical Properties of Succinonitrile-Based Gel Polymer Electrolytes: Role of Ionic Liquid Addition

“…Further, the other attractive features of SN-like plastic crystalline materials are their vanishingly small vapor pressure (hence the loss of electrolyte by evaporation is avoided) and minimal flammability leading to the safety concern. Despite having substantially high ionic conductivity at ambient temperature and various other properties mentioned above, an ideal material that exists in its plastic phase over a temperature range from 0 to 100 °C is yet to be found . Furthermore, pure SN-based electrolytes lack the mechanical properties to provide flexible-film-like shape to the electrolytes, which are most appropriate for their applications in ionic devices.…”

“…Despite having substantially high ionic conductivity at ambient temperature and various other properties mentioned above, an ideal material that exists in its plastic phase over a temperature range from 0 to 100 °C is yet to be found. 35 Furthermore, pure SN-based electrolytes lack the mechanical properties to provide flexible-film-like shape to the electrolytes, which are most appropriate for their applications in ionic devices. In order to provide a definite shape, particularly in the form of a free-standing and flexible film, the entrapment of such electrolytes in polymer hosts, for example, PEO, PAN, PVdF-HFP, and so forth, is a useful approach.…”
