• Applications of Ionic Liquids as Electrolyte for Energy Devices

抄録

  In this paper, our studies to apply ionic liquids (ILs) as electrolyte in energy devices such as lithium ion batteries (LIB) and H₂/O₂ fuel cells (FC) are reviewed. Typical ionic liquids are non-volatile and thermally stable with high ionic conductivity without any molecular solvents and thus can be expected as next generation electrolyte. It is anticipated that safety of LIB can be improved by using Li⁺-conducting ILs and that FC can be operated under non-humidifying conditions by using H⁺-conducting ILs. By our studies, we could find important characteristics of ionic liquids for applying to energy devices. For LIB application, we revealed that glyme-Li salt complexes exhibit acceptable ionic conductivity with high Li⁺ transference number, while for PEFC application, we found that protic ILs exhibit high electrochemical activities for fuel cell reactions. The performances of LIB and non-humidifying FC using ILs were promising for the future developments.<br>
