Hydrothermal Synthesis and Electrochemical Performance of MoO2 as Anode Materials for Lithium-ion Batteries

Keywords： lithium-ion batteries , anode material , MoO2 , electrochemical performance

以四水合钼酸铵(AHM)、乙二醇(EG)为原料,采用水热法合成MoO2材料,用x射线衍射(XRD)、扫描电子显微镜(SEM)、电化学测试研究材料的结构和电化学性能.结果表明,水热法合成的MoO2粒径为20～30 nm,材料表现出良好的电化学性能.首次放电比容量为664.3 mA h/g,充放电效率较高,首次充放电的库伦效率高达94％,在20个充放电循环过后,仍有较高的容量保持率,MoO2作为锂离子电池负极材料展现出良好的容量存储和循环性能.
