Fabrication of hierarchical core/shell MgCo2O4@MnO2 nanowall arrays on Ni-foam as high–rate electrodes for asymmetric supercapacitors
Design and fabrication of a hierarchical core/shell MgCo 2 O 4 @MnO 2 nanowall arrays on Ni-foam by a facile two-step hydrothermal method. The electrochemical measurements prove these composites with MnO 2 definitely offer better supercapacitive performance of the MgCo 2 O 4 electrode material. The...
