The composites anodes Received in revised form 5 February 2016 −1 −1 show a reversible capacity of 450 mAh g after 150 cycles at the current density of 200 mA g , which Accepted 5 February 2016 −1 is approximately two times of pure TiO nanotubes. Even at a high current density of 3200 mA g , the Available online 9 February 2016 −1 composite anodes still exhibit a good capacity of 198 mAh g , more than three times higher than that of pure TiO nanotubes.
