Abstract

We utilize high-conductivity Te nanowire arrays grown on flexible carbon fibre to fabricate a hybrid Te/Au/MnO2 core–shell nanostructure as a supercapacitor electrode. Electrochemical measurements show that a very high specific capacitance of 930 F g−1 (based on the mass of MnO2) is obtained for Te/Au/MnO2 core–shell nanostructures. In addition, our Te nanowire array-based supercapacitor exhibits excellent rate capability and long term cycling stability. Uniquely, high-density Te nanowire arrays offer a high specific surface area to the hybrid Te/Au/MnO2 core–shell nanostructure which profoundly increases the specific capacitance. These results indicate that Te nanowire array/Au/MnO2 core–shell nanostructures show promising applications as electrode materials for energy storage.
