| Outline of Final Research Achievements |
Organic materials has attracted much attention as the electrodes in low-cost, environmentally-friendly and high-energy-density batteries. In this study, we analyzed the crystal structural change in organic electrode, and revealed that the crystal growth of organic compound during charge-discharge cycling can become a dominant mechanism of battery degradation. To avoid the organic crystal growth, the control of interface between electrode and electrolyte was effective. Moreover, by applying the organic active materials to electrochemical flow capacitor, the capacitance enhancement was achieved.
