Supercapacitive properties of composite electrode consisting of activated carbon and a quinone-containing conducting additive |
| 초록 |
A quinone-containing conducting additive, 2,5-bis((2-(1H-indol-3-yl)ethyl)amino)cyclohexa 2,5-diene- 1,4-dione (HBU) is synthesized and mixed with activated carbon as an active material to yield a composite supercapacitor electrode. Due to the extra redox reaction of hydroquinone/quinone couple, the supercapacitor adopting the composite electrode shows the enhancement of the electrochemical specific capacitance up to about 130 F g1 in the scan range of 100–1000 mV s1 and over the repeated redox processes for 1000 cycles at 100 mV s1, compared to the case of activated carbon electrode alone (about 100 F g1). The composite with the HBU is also electrochemically stable in the charge/discharge process and thereby can be highly recommended for supercapacitor electrode additive. |
