These organic based electrolytes possess favorable features such as high ionic conductivities. However, carbonates are flammable which pose safety concerns and this limits their operative temperature range . For these reasons, there have been a lot of research interests to develop alternative electrolytes that have improved safety and that would be able to work in a broader operative temperature range. Recently, a large number of alternative electrolytes have been suggested. Among them, ionic liquids (ILs) have been proposed as one of the solutions to the above safety concerns, mainly because of their high thermal and chemical stability, large electrochemical stability window, and their negligible vapor pressure . The structural, thermodynamic , and dynamic properties of both pure ionic liquids and their mixtures with other compounds have been studied and documented by different authors that make use of both experimental and theoretical calculations.
