| Outline of Final Research Achievements |
Alkali metal salts and solvents (ligands) form complexes (solvates) in certain molar ratios. The complexes having melting points below room temperature are called solvate ionic liquids (SILs).The interaction between the metal ions and solvents were elucidated using spectroscopic and computational methods. The concentration of salt exceeds 3 mol/L in SILs. Almost all the solvent molecules are involved in the solvation of the metal ions in SILs, and free (uncoordinated) solvents scarcely exist. This results in the very low activity (chemical potential) of the solvents in the SILs. This study revealed that the activity of solvent gives significant effects on the electrochemical reaction process at the electrode/SIL interface.
