Abstract: | This paper demonstrates a low temperature solvothermal method for the synthesis of a layered spheric TiO2. The crystal structure and morphology of the material were characterized by using X-ray diffraction (XRD) and scanning electron miscopy (SEM). Electrochemical performances of the TiO2 when used as anode material in lithium ion batteries were investigated by galvanostatic charge/discharge and cyclic voltammetry experiments. A discharge capacity of 179 mAh g−1 was obtained in the potential range between 3.0 and 1.5 V. No significant capacity decay was observed in the successive 30 cycles showing satisfactory cycling performance of the electrode. |
