▎ 摘　　要

Rational design and controllable synthesis of TiO2 based materials with unique microstructure and excellent electrochemical performance for Na-ion batteries have been imperative requirement at present. In our work, TiO2 with graphene-like (TiO2-GL) structure has been synthesized from P25 (commercial TiO2 with phases hybriding) by skillful controlled hydrothermal synthesis conditions. As a result the obtained TiO2-GL still possesses hybrid phases, and delivered high reversible capacity, fantastic cycling performance and superior rate capability for Na-ion battery system. When discharged for 100 cycles at current density of 100 mA g(-1), the TiO2-GL shows a reversible capacity of about 150 mAh g(-1). Even when the current density is increased to 500 mA g(-1), a very stable and extraordinarily high reversible capacity of 100 mAh g(-1) can be delivered. Obviously, the excellent performance are owing to the synergistic effect of hybrid phases and graphene-like structure. (C) 2016 Published by Elsevier B.V.
