제목 | The investigation to contents of active materials in flowable electrode for cyclic ultracapacitor |
초록 | Supercapacitors based on electrochemical double-layer capacitance (EDLC) are promising electrical ESS owing to their specific advantages, such as a long lifespan, fast response, and high power density. They have long been used in many industries, but their short usage times due to their low energy density levels clearly represent limitations when used as an ESS component in renewable energy plants. As part of the effort to overcome the low energy density limitation, the new concept of device combining a supercapacitor and a flow battery system has recently been developed. In this study, we demonstrate the optimal composition of flow electrode in cyclic ultracapacitor to improve electrochemical performance of flow electrode by optimizing ratio between active materials and electrolyte (1M TEABF4 in acetonitrile). Therefore, we obtained significant value in non-flow cell test. The highest value of specific capacitance which was around 156F·g-1 was measured at 14 wt%. |
