Outline of Final Research Achievements |
Structures and dynamics of ionic liquid/electrode interfaces, where electrochemical reactions occur, have been investigated by using surface-enhanced infrared absorption spectroscopy. As a result, "hysteresis behavior" was found, which means that the exchange between cations and anions at the first ionic layer on the electrode surface occurs at different electrode potential depending on the direction of the potential scan. This behavior is affected by the size of constituent ions of the ionic liquid. A kind of resistive interaction between ions for exchange of ions results in the formation of ionic layer on the surface which can interfare electrochemical reactions. We also investigated the dissolvation states of water and Li+ and their effect on the interfacial structures.
