| Outline of Final Research Achievements |
In order to understand transport properties over a wider range of temperature and pressure, we have developed in-situ analytical tools such as pulsed-field-gradient nuclear magnetic resonance spectroscopy (pfg-NMR) and electrochemical measurements. By means of pfg-NMR developed, self-diffusion coefficients of ionic species in protic ionic liquids and lithium battery electrolytes have been determined. The intermolecular interactions in such complex liquids have been understood based on the self-diffusion results in combination with the other transport properties, viscosities and electrical conductivities. Moreover, electrical conductivities in ionic liquids saturated with CO2 at vapor-liquid equilibrium conditions have been measured. In view of solute-solvent interactions, the effect of CO2 dissolution on the transport property have been discussed.
