논문 초록 (Abstract)
Di(1-aminopyrene)quinone (DAQ) as a quinone-containing conducting additive is synthesized from a solution reaction of 1-aminopyrene and hydroquinone. To utilize the conductive property of DAQ and its compatibility with activated carbon, a composite electrode for a supercapacitor is also prepared by blending activated carbon a nd DAQ (3:1 w/w), and its supercapacitive properties are characterize d based on the cyclic voltammetry and galvanostatic charge/discharge. As a result, the composite electrode adopting DAQ exhibits superio r electrochemical properties, such as a higher specific capacit anceof up to 160 F.g(-1) at 100 mV.s(-1), an excellent high-rate capabi lity of up to 1,000 mV.s(-1), and a higher cycling stability with a capa citance retention ratio of 82% for the 1,000th cycle.
