| 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 and DAQ (3:1 w/w), and its supercapacitive properties are characterized based on the cyclic voltammetry and galvanostatic charge/discharge. As a result, the composite electrode adopting DAQ exhibits superior electrochemical properties, such as a higher specific capacitance of up to  at  , an excellent high‐rate capability of up to  , and a higher cycling stability with a capacitance retention ratio of 82% for the 1,000th cycle. |
