Composite Supercapacitor Containing Tin Oxide and Electroplated Ruthenium Oxide

Abstract
A supercapacitor electrode was synthesized by cyclic voltammetric plating of onto a porous and highly conductive, Sb (6 mol %)-doped particulate substrate that possessed a large surface area A specific capacitance of 930 F/g for the component in 1 M and an overall specific energy of at a specific were achieved by an optimized crystallization protocol (150°C). Comparative studies demonstrated that this composite electrode exhibited a far superior performance to electrodes having similarly plated onto either smooth Ti or porous conductive carbon black. © 2003 The Electrochemical Society.
