Electrochemical Properties of MnO[sub x]–RuO[sub 2] Nanofiber Mats Synthesized by Co-Electrospinning

Abstract

We report on the fabrication and characterization of layer-by-layer stacked nanofiber mats via co-electrospinning and their potential application for electrochemical capacitors. The morphology of multistacked 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 fiber mats, offers a facile ion pathway and provides a fast electron pathway. The electrochemical capacitors utilizing co-electrospun fiber mats exhibited a high specific capacitance of 208.7 F/g at 10 mV/s.
