Ionic liquids high temperature fused salts

To this end, we review the physics of high temperature fused salts and draw on observations made in these systems to understand the microscopic structure of ionic liquids. We also review some physics of glass-forming liquids, focusing on concepts necessary to understand structural and dynamic inhomogeneity in ILs. We provide a broad review of attempts to characterize ILs empirically, and discuss those results with reference to simulation and theoretical studies. The overall objective of this study is to develop a conceptual toolbox that can be used to interpret experimental results in ILs and help identify useful new questions for the field. To this end, we present a series of principles describing the nature of solvation in ionic liquids at the conclusion of this chapter. 

Another class of ionic liquids consists of the molten oxides. These are highly conducting liquids formed by the addition of a metal oxide (e.g., LijO) to a non-metal oxide (e.g., SiOj). These systems melt at much higher temperatures than the molten salts. Some properties of the molten oxides are shown in Table 5.5. To develop a perspective on the properties of liquid electrolytes, some properties of water, liquid sodium, an aqueous solution of NaCl, fused NaCl, and a mixture of fused NajOand SiOj are shown in Table 5.6.
