摘要
采用微乳液辅助溶剂热法一步合成了纺锤状Fe_3O_4/C复合负极材料。利用X射线衍射仪(XRD)、场发射扫描电子显微镜(FE-SEM)和透射电子显微镜(TEM)对样品的物相和微观形貌进行了表征。通过扣电测试仪测试了样品的循环性能,结果表明:190℃反应10h所得产物循环100周容量保持率高达99.71%,预示其在锂离子电池领域具有广阔的应用前景。
The spindle-shaped Fe3O4/C composite negative electrode material was synthesized by means of microemulsion assisted solvothermal method.The phase and microstructure of the samples were characterized by x-ray diffraction(XRD),field emission scanning electron microscopy(FE-SEM)and transmission electron microscopy(TEM).The cycle performance of the sample was tested by the deduct tester,and the results show that the100-week capacity retention rate of the product is up to99.99%at190℃for10h,indicating that it has a wide application prospect in the field of Li-ion battery.
