“…The slope of conductivity decrease in the acid ic melts is less sharp than that in the basic melts, be cause the viscosity decrease with increasing AI2CI7 is partly com pensated by the AICI4 produced by the de com position of AI2CI7 . The conductivities of A1C13-BPC melts agree well with the data of previous w ork [2,3], which demonstrates the practicability and precise ness of the present com puterized measurem ent system. Figure 8 shows that the conductivity is m axim um at 50 mol% AICI3 and 30 to 80 °C.…”

The conductivities of the binary room-temperature molten salt systems AlCl3-yV-«-butylpyridinium chloride (BPC), AlCl3-l-ethyl-3-methylimidazolium chloride (EMIC) and AlCl3-benzyltriethylammonium chloride (BTEAC) have been measured at different temperatures and compositions by a d.c. fourprobes method.There is a maximum of the conductivity at 50 mol% A1C13 in the A1C13-BPC and A1C13-EMIC systems at 40 to 80 °C, their activation energies being relatively low (20.79 and 14.76 kJ/mol, respec tively). As to the A1C13-BTEAC system, there is an irregular change in the conductivity at 40-70 mol% A1C13 in the temperature range 50 to 80 °C. The conductivities of the three RTMS are in the order A1C13-EMIC > A1C13-BPC > A1C13-BTEAC, the reason being discussed.

“…14 Polymer electrolytes of ILs (ion gels) are polymer networks in which ILs are incorporated. In the initial stages of the study, chloroaluminate-based ILs were used, 14,28 but later, non-chloroaluminate-based ILs [29][30][31] were included. Compatibility between ILs and polymers is crucial for the preparation of polymer electrolytes.…”

Ionic liquids (ILs) are defined as salts that have melting points lower than 100°C. Most are organic salts, and these may be designed and tailored to have suitable properties. ILs are recognized as a third group of solvents (and electrolytes), after water and organic solvents. They are characterized by their unique properties such as nonvolatilities, high thermal stabilities, and high ionic conductivities. In this article, our work on the design and preparation of ILs is briefly reviewed. The concept of ionicity is proposed as a metric to characterize the basic nature (dissociativity) of ILs, which is affected by the Lewis acidity/basicity of cations/anions (i.e., coulombic interactions), the directionality of interactions between cations and anions, and van der Waals interactions between ions. The ionicity of ILs is dominated by a subtle balance between coulombic and van der Waals interactions, which clearly discriminates ILs from conventional high-temperature inorganic molten salts. Here, the design of protic ILs for fuel cell electrolytes, electron-transporting ILs for dye-sensitized solar cell electrolytes, and Li + -conducting solvate ILs for lithium battery electrolytes are discussed based on an understanding of the fundamental properties of ILs. Furthermore, the combination of ILs with polymers and colloidal particles affords intriguing quasi-solid materials (ion gels), and the ion transport in these gels is decoupled from the mechanical relaxation time of these materials, yielding new solid electrolytes. The possibility of temperature and photo-sensitive solubility dependence of polymers in ILs allows the creation of stimuli-responsive materials. Finally, protic ILs/protic salts are demonstrated to be good precursors for N-doped carbon materials.
