| Outline of Final Research Achievements |
The purpose of this study is to propose a new design concept for liquid electrolytes of next-generation high-energy and high-power secondary batteries. In addition to establishing the concept of solvate ionic liquids, ionic conductivity of solvate ionic liquids was increases to that of conventional organic electrolytes with addition of low-polar and non-coordinating solvents. We also synthesized novel redox-active solvate ionic liquids composed solely of complex cations and anions, and semi-liquid type lithium secondary batteries were demonstrated with the redox-active solvate ionic liquids as catholyte. Furthermore, quasi-solid electrolytes of solvated ionic liquids were prepared by combining them with polymers and nanoparticles.
