| 摘 要： | 以水杨酸为模板剂和还原剂,采用水热法制备得到了一种MoO3纳米带/RGO复合材料。利用XRD、SEM、TEM、拉曼光谱、恒流充放电、交流阻抗等手段对样品的结构、形貌以及电化学性能进行表征。测试结果表明,MoO3纳米带/RGO复合材料作为锂离子电池负极材料,在50mA·g-1的电流密度下可逆比容量为1000mAh·g-1,循环50次后比容量还保持在950mAh·g-1,相比于MoO3纳米带其容量保持能力和循环性能得到了显著改善。

| Abstract: | MoO3 nanobelts/RGOcomposites were obtained through a facile and efficient hydrothermal procedure by using organic compound sodium salicylate as both structure-directing agent and reducing agent. The crystal structure, morphologies and electrochemical performances of the as-prepared samples were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, galvanostatic charge/discharge test and electrochemical impedance spectroscopy (EIS). The hybrid material shows a high specific capacity of 1000 mAh·g-1 with a good cycling stability as an anode material for lithium ion batteries, which has a much enhanced performance compared to bare MoO3 nanobelts. |
