Abstract
Fe2O3 is one of the promising negative electrodes for asymmetric supercapacitors. But the rather low conductivity and poor cycling stability hinder its practical application. Herein, we report a facile electrochemical deposition technique to prepare porous Fe2O3 nanosheets on carbon fabric (CF-Fe2O3). The obtained Fe2O3 displays highly porous nanosheet structure with reduced ion diffusion length and significantly enhanced conductivity. As a flexible supercapacitor electrode, the CF-Fe2O3 hybrid electrode delivers a large areal capacitance of 1.56 F cm
