논문 초록 (Abstract)
"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 g(-1) in the scan range of 100-1000 mV s(-1) and over the repeated redox processes for 1000 cycles at 100 mV s(-1), compared to the case of activated carbon electrode alone (about 100 F g(-1)). The composite with the HBU is also electrochemically stable in the charge/discharge process and thereby can be highly recommended for supercapacitor electrode additive. (C) 2015 Elsevier B.V.
