摘要：

通过表面活性剂辅助水热合成了钼酸镧钠负极材料，利用X射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、循环伏安(CV)测试等对样品结构和电化学性能进行了研究.结果表明，与pH=10相比，pH=6时制备的钼酸镧钠负极材料具有更好的电化学性能，其在电流密度为0.1 A/g时，容量可达356.7 mAh/g，循环后库伦效率接近100 %.

Abstract：

The sodium lanthanum molybdate anode materials were prepared by surfactant-assisted hydrothermal synthesis.The structure and electrochemical performance of samples were investigated by X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FTIR) and cyclic voltammetry(CV) test.The results showed that the sodium lanthanum molybdate anode material prepared at pH=6 had better electrochemical performance than that prepared at pH=10.At a current density of 0.1 A/g,its capacity could reach 356.7 mAh/g,and the coulombic efficiency after cycling was close to 100 %.
