In this work, we developed an eco-friendly strategy for preparing Co3O4 nanowires. The process consisted of two steps: controllable synthesis of metal cobalt nanowires followed by a facile air-oxidization step. The 1D nanowire structure with a high aspect ratio was easily achieved via a magnetic-field-assisted self-assembly of cobalt ion complexes during reduction. After air-calcinations, the Co3O4 nanowires were prepared in large scale and ready to be used as the anode material for lithium-ion batteries. The Co3O4 nanowires, which possessed a length ranging from 3 to 8 mu m with the aspect ratio more than 15, exhibited a reversible lithium storage capacity up to similar to 790 mAh/g when using a small amount of defect-free graphene flakes as conductive additives. The superior electrochemical performances were ascribable to the synergistic flat-on effect between the 1D nanowires and the 2D graphene. Therefore, the Co3O4 nanowire/graphene composite holds promising application for lithium-ion batteries.
