Highly Stable Gully-Network Co₃O₄ Nanowire Arrays as Battery-Type Electrode for Outstanding Supercapacitor Performance.

ABSTRACT: 3D transition metal oxides, especially constructed from the interconnected nanowires directly grown on conductive current collectors, are considered to be the most promising electrode material candidates for advanced supercapacitors because 3D network could simultaneously enhance the mechanical and electrochemical performance. The work about design, fabrication, and characterization of 3D gully-network Co₃O₄ nanowire arrays directly grown on Ni foam using a facile hydrothermal procedure followed by calcination treatment will be introduced. When evaluated as a binder-free battery-type electrode for supercapacitor, a high specific capacity of 582.8 C g^-1 at a current density of 1 A g^-1, a desirable rate capability with capacity retention about 84.8
