A new hybrid nanostructure of porous cobalt monoxide nanowire @ ultrathin nickel hydroxidenitrate nanoflake is directly synthesized on a 3D foam by facile two-step hydrothermal route, which demonstrates specific capacitance ∼798.3 F g−1 at the current density ∼1.67 and good rate performance when used as electrode material for supercapacitors. The loss less than 5% after 2000 charge–discharge cycles.
