A pioneering effort has been made to develop F--ion-doped anatase TiO2 with a spherical shape and mesoporous structure synthesized by a unique, low-temperature Urea-assisted hydrothermal synthesis The electrochemical anode performance of pristine TiO2 for lithium-ion batteries was improved significantly by utilizing F--Ion doping. TiO2 doped with 10 mol % fluorine ions achieved a reversible capacity of 157 mA h/g after 100 cycles In addition, the rate capability of the F--ion-doped TiO2 was encouraging, with a stabilized capacity of 144 mA h/g at 30C (C rating) of charge (Li extraction).
