Novel anatase@TiO2（B） hybrid nanowires have been synthesized by a facile aqueous alkali hydrothermal method,followed by acid washing and heating.The as-prepared anatase@TiO2（B） hybrid nanowires deliver a highly reversible capacity of 196mAh/g after 100 cycles at 30mA/g（0.1C） and excellent rate capability as high as 125mAh/g when cycled at 4500 mA/g（15C）.Owing to the excellent electrochemical performance,anatase@TiO2（B） hybrid nanowires could be promising anode materials for lithium ion batteries.
