An initial reversible capacity of 185 mAhg− 1 was obtained at C/2, with an initial irreversible loss of 15%. The composite showed a high stability upon cycling, with 92% retention of the capacity after 37 cycles, and good high rate capability, with a capacity of 102 mAhg− 1 at 10C. The performance of the CNTs–TiO2−δ composite was compared to that of pristine commercial TiO2 and to that of oxygen-deficient TiO2 − δwith the aim of identifying the source of the improvement. Both TiO2−δ and CNTs network were found to contribute to the enhanced electrochemical performance of CNTs–TiO2−δ composite.
