The morphology of multistacked MnOx-RuO2 fiber mats provides high porosity for the efficient permeability of electrolyte into the inner structure while maintaining a high surface area for enhanced surface activity. In an electrochemical capacitor using MnOx-RuO2 fiber mats, MnOx offers a facile ion pathway and RuO2 provides a fast electron pathway. The electrochemical capacitors utilizing co-electrospun MnOx-RuO2 fiber mats exhibited a high specific capacitance of 208.7 F/g at 10 mV/s. (C) 2009 The Electrochemical Society.
