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