Carbon-wrapped CuO is synthesized by a facile pyro-synthesis method without using a conventional carbon source to overcome the capacity fading issue of CuO nanoparticles. The microstructure analysis shows that the sample is fully wrapped by a carbon layer. The resultant carbon-wrapped CuO nanocomposite as an anode exhibits high reversible capacity with excellent cycling stability (437.1 mAh/g at 0.25 C and 365.2 mAh/g at 1.0 C after 100 cycles) and good rate capability. It is believed that the synergistic effect of CuO and carbon is responsible for the enhanced electrochemical performance of the nanocomposite electrode.
