We report for the first time a facile and direct synthesis of large-scale cobalt monoxide (CoO) porous nanowire arrays (NWAs) with robust mechanical adhesion to flexible conductive Substrate (Ti foil) by a two-step method. Significantly raw salt Cubic CoO of high quality from the complete pyrolysis of cobalt-hydroxide-carbonate (precursor) is achieved. When serving as lithium-ion battery electrodes in the absence of any ancillary materials (carbon black and binder), the as-obtained well-aligned CoO NWAs, possessing both the completely reversible electrochemical properties and unique advantages originating from integrated one-dimensional (1D) nanostructured architecture, exhibit good high-rate capability at a rate of 1 C (716 mA/g), 2 C (1432 mA/g), 4 C (2864 mA/g), and 6 C (4296 mA/g), respectively.
