摘　　要：以钼酸铵和浓硝酸为反应起始物,通过简单水热反应合成了具有层状结构的MoO3微米材料,运用X射线衍射、扫描和透射电镜对其物相组成、形貌和结构等进行了表征,并对其作为锂离子电池负极材料的电化学储锂特性进行了研究。结果表明,MoO3呈片层状结构,尺度为微米级,其电化学储锂性能较为优异,经过40个循环后,其可逆容量高达720 mAh/g。MoO3 Microparticles with lamellar structure were prepared by a facile hydrothermal method u- sing ammonium molybdate and nitric acid as the starting materials. The composition, morphology and structure of the synthesized material were investigated by means of X-ray diffraction, scanning electron mi- croscopy and transmission electron microscopy, and the electrochemical performance of the synthesized sample was studied as an anode material for lithium ion batteries. The results show that the synthesized MoO3 displays a lamellar structure with micro-size. Electrochemical tests show that the material has rela- tively excellent electrochemical performance. After 40 cycles, the reversible capacity is up to 720 mAh/g.
