【摘要】 采用微乳液辅助溶剂热法一步合成了纺锤状Fe₃O₄/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。更多还原

【Abstract】 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 the 100-week capacity retention rate of the product is up to 99. 99 % at 190 ℃ for 10 h, indicating that it has a wide application prospect in the field of Li-ion battery.更多还原
