| 제목 | The investigation of flow-able electrode to improve electrochemical performance of cyclic ultracapacitor |
| 초록 | Renewable-energy sources are being used in various industrial fields, but these sources are intermittent and often unpredictable. Due to these weaknesses of renewable energy sources, the necessity to application with energy storage systems (ESS) comes to the fore. Owing to advantages of large scale energy storage system, flow batteries are most promising secondary battery since past decades. But they have to improve performance which is high cost, low power density and short life span to commercialize more industrial fields. Thus, electrochemical flow capacitor was found by researchers to solve these problems. In this study, we investigate to increase electrochemical performance of flow-able electrode which was injected cyclic ultracapacitor by optimizing ratio between active materials and electrolyte (1M TEABF4 in acetonitrile). Therefore, the highest value of specific capacitance which was around 156F·g-1 was measured at 14 wt%. |
