摘要
Rational design and controllable synthesis of electrode materials with unique microstructure and excellent electrochemical performance for Alkali metal ion batteries being crucially desired.[1-4] In our work, TiO_2 with Graphene-like(TiO_2-GL) structure has been synthesized from P25(commercial TiO_2 with phases hybriding) by skillful control hydrothermal synthesis conditions. As a result the obtained TiO_2-GL still has phase hybriding, and demonstrated high reversible sodium storage capacity, fantastic cycling performance and superior rate capability.[5] When discharged/charged for 100 cycles at current density of 100 m A·g~(-1) the TiO_2-GL shows a reversible capacity about 150 m Ah·g~(-1). Even when the current density is increased to 500 m A·g~(-1), a very stable and extraordinarily high reversible capacity of 100 m Ah·g~(-1) can be delivered. Obviously, the excellent performance are owing to the synergistic effect of phases pybriding and Graphene-like structure.
