Abstract
This paper reports a simple-assembling synthesis of Cu x O/C composite as the anode for lithium-ion batteries. The Cu x O/C composite can be easily attained through using cotton as the template. Used as the anode material, the Cu x O/C electrode has shown a relatively stable electrochemistry performance compared with the pristine CuO electrode. The cycling test results showed that the Cu x O/C electrode achieved the steady specific capacity values of 381 mAhg −1 at 335 mAg −1 after 350 cycles while the capacity of the CuO electrode decreased after several cycles before it increased to 375 mAhg −1 . This Cu x O/C anode electrode stability is considered attributed to its core/shell structure, which can help keep the electrode structure stable during cycling.
