| Outline of Final Research Achievements |
I focused on highly concentrated electrolytes within crystallinity gap, and studied their unusual functionalities. Concentrated electrolytes, having been outside the research mainstream because of their decreased ionic conductivity, are demonstrated to have various unusual functionalities beneficial for battery application. In particular, the corrosion prevention of aluminum current collectors at high potential was studied in detail from both experimental and theoretical approaches. This work proposes coordination states as a new axis of electrolyte design.
