An asymmetric anthraquinone-modified carbon/ruthenium oxide supercapacitor

---

a b s t r a c t
An asymmetric supercapacitor with improved energy and power density, relative to a symmetric Ru
oxide device, has been constructed with anthraquinone-modified carbon fabric (Spectracarb 2225) as the
negative electrode and Ru oxide as the positive electrode. The performance of the supercapacitorwas characterized by cyclic voltammetry and constant current discharging. Use of the anthraquinone-modified
electrode extends the negative potential limit that can be used, relative to Ru oxide, and allows higher
cell voltages to be used. The maximum energy density obtained was 26.7Whkg−1 and an energy density
of 12.7Whkg−1 was obtained at a 0.8Acm−2 discharge rate and average power density of 17.3kWkg−1.
The C-AQ/Ru oxide supercapacitor requires 64% less Ru relative to a symmetric Ru oxide supercapacitor.
