1 Results Room-temperature Ionic liquids (RTILs) are special class of compounds, where a combination of cations and anions produces neutral, stable and viscous liquids with high ionic conductivity. Widely spread applications are proposed to use conductors, electrolytes, clean solvents and others. Especially, RTILs are expected to be safe electrolytes in the ion-lithium batteries. In this study, NMR methods are used to clarify the basic properties of the individual movements of the anions and cations of the imidazolium ionic liquids which have been demonstrated to be valid as the lithium electrolytes. The ion self-diffusion and the molecular reorientational motions are interpreted by the mutual ion interactions calculated by ab initio molecular orbital method. 1 Results Room-temperature Ionic liquids (RTILs) are special class of compounds, where a combination of cations and anions produces neutral, stable and viscous liquids with high ionic conductivity.
