Synthesis of quinone derivatives and its application to redox electrode
Bong Ho Lee and Yeajoon Bon
Hanbat National University, South Korea
Physical mixing of activated carbon (AC) and a quinone derivative, 2, 5-bis (pro-2-ny-1-ylamino) cyclohexa-2, 5-diene-1,
4-dione (coded HBU-281) was used to design a composite electrode for supercapacitors. The process proves to be simple
and cost-effective because it demands only the initial synthesis of the organic additive. The electrode properties were probed in
terms of composite composition, redox behavior, specific capacitance, and cycle life. The capacitance performance of the AC
electrode is enhanced due to the extra redox reaction of hydroquinone/quinone couple of HBU-281. AC facilitated electron
distribution to the HBU-281 making pronounce its redox activity. The composites due to the synergistic effect of AC and
HBU-281 gave higher capacitance and indicating excellent cycle stability than the individual electrodes. These findings led to
the conclusion that physical mixing of AC and HBU-281 can be adopted to design cheap and excellent composite electrodes
for supercapacitor.
