TixSn1−xO3 solid solution as an anode material in lithium-ion batteries

TixSn1−xO3 solid solutions were prepared by a hydrothermal process. The morphologies and structures of TixSn1−xO3 solid solutions were investigated by scanning electron microscope, transmission electron microscope and X-ray diffraction measurements. The electrochemical properties of TixSn1−xO3 solid solution electrodes with different Sn/Ti ratios were examined by a variety of electrochemical testing methods. It was found that, the TixSn1−xO3 solid solution showed not only higher specific capacity of 506 mAh g−1 after 30 cycles but also better cycle performance, superior than the pure SnO2 electrode, which can be ascribed to the stable cyclability of TiO2 and the high reversible capacity of nanosized SnO2. The TixSn1−xO3 solid solutions would be a potential candidate as anode material for a new generation lithium ion batteries.
