Electrochemical Deposition of Nanostructured Indium Oxide:  High-Performance Electrode Material for Redox Supercapacitors

Nanostructured and nanorod-shaped three-dimensional In2O3 were deposited on stainless steel (SS) by a novel potentiodynamic method at a high scan rate of 200 mV s-1. In2O3/SS electrodes were found to exhibit high specific capacitance, high power density, and long-term stability when used as active electrode materials for redox supercapacitors.
