| Outline of Final Research Achievements |
Electron-transfer processes of quinones characterized by their electrochemical reversibility and rapid reaction rates were employed to develop organic anode-active materials for energy storage, based on electron self-exchange reactions in the polymer layer. Polymers bearing anthraquinones as pendant group per repeating unit gave rise to highly efficient charge transport properties to allow fabrication of organic rechargeable air battery, giving insight into the nature of n-type charge storage with the polymers. The polymers were developed according to (i) design of novel n-type redox-active groups, (ii) analyses of electron- and ion-transport processes, (iii) precise control of these processes for rectification at heterojunctions, and (iv) establishment of charge storage with polymers characterized by rocking-chair-type migration of electroneutralizing ions and bipolar charging capabilities, which led to (v) rational design of a series of high-density energy-storable polymers.
