采用机械化学还原法，由 Sb2O3、Ti 和碳粉制备了嵌入 TiO2 的 Sb 基纳米结构复合材料，并作为可充电锂离子电池的负极材料进行了评估。 X射线衍射、X射线光电子能谱和高分辨率透射电子显微镜分析表明，Sb/TiO2/C纳米复合材料由纳米晶Sb、金红石-TiO2和无定形碳组成。电化学测试表明，Sb/TiO2/C纳米复合电极的电化学性能优于纯Sb电极。
An Sb-based nanostructured composite with embedded TiO2was prepared from Sb2O3, Ti, and carbon powders using a mechanochemical reduction method and was evaluated as an anode material in rechargeable Li-ion batteries. X-ray diffraction, X-ray photoelectron spectroscopy, and high-resolution transmission electron microscopy analyses reveal that the Sb/TiO2/C nanocomposite is composed of nanocrystalline Sb, rutile-TiO2, and amorphous carbon. Electrochemical tests show that the electrochemical performance of the Sb/TiO2/C nanocomposite electrode is superior to that of the pure Sb electrode.
