we provided a facile approach to prepare a new kind of CuO nanoflower structures, which was self-assembled by the CuO nanobelts.The process conditions were also investigated to find that the product morphologies were strongly affected by treatment conditions.The lithium storage performances of the CuO nanoflowers were studied, and the sample treated by KOH solution exhibited the best properties: a reversible capacity of c.a.800 mAhg-1 after 100 cycles at a current density of 50mAg-1, which is higher than those of the CuO nanostructures that have been reported.The great cycle stability and high-rate performance, which is better than the traditional commercial carbon anode materials,suggesting that the CuO nanostructures synthesized by this method is a promising anode material for lithium-ion batteries.
