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. Financial support by the the EU and the state NRW in the framework of the HighTech.NRW program for funding of CES, the DFG in the framework of SPP1473 (Wendelib) and the Ruhr-University Research School is gratefully acknowledged. application/pdf eng Elsevier Electrochemistry Communications.
