| Research Abstract |
Polyimides were found to exhibit excellent redox capability per repeating unit when they were made into a carbon nanocomposite layer at a molecular level. The reversible redox reaction obtained by placing the polyimide/carbon composite layer on a current collector was applied to the charge-storage process of anodes in organic batteries. A variety of polymers with an ultimate density of organic redox-active sites were synthesized, and their basic properties as the anode-active materials were determined. Enhanced charge transfer process accomplished by the precise control of mass-transfer process led to rapid and large-capacity charge storage with the polymers. A design strategy of electrode-active materials with excellent ionic migration processes was proposed, which allowed significant reduction of the amount of electrolytes in batteries.
