Abstract
A supercapacitor electrode was synthesized by cyclic voltammertric plating of RuO2 onto a porous
and highly conductive, Sb (6 mol %)-doped SnO2 particulate substrate that possessed a large surface
area (75 m 2 /g). A specific capacitance of 930 F/g for the RuO2 component in 1 M H2SO4(aq) and an
overall specific energy of ~0.5 Wh/kg at a specific power ≥1.5 kW/kg were achieved by an optimized
crystallization protocol (150 ℃). Comparative studies demonstrated that this composite electrode
exhibited a far superior performance to electrodes having RuO2 similarly plated onto either smooth Ti
or porous conductive carbon black.
