| Outline of Final Research Achievements |
In this study, we hybridized redox organic compounds, 2,5-dichloro benzoquinone (DCBQ), with porous carbon black, ketjen black (KB), to prepare high-performance electrochemical capacitor electrodes through a solvent-free method. Through this method, the KB and DCBQ weight ratios can be accurately controlled because DCBQ molecules are completely adsorbed inside the pores of KB in a gas phase without any expansion of the KB particles. Electrochemical measurements revealed that the pseudocapacitance of DCBQ exhibited the higher volumetric capacitance and power density and longer cycle lifetimes than the electric double-layer capacitance, both of which are generated inside the pores of KB.
