摘　　要：采用电纺技术结合后续高温煅烧过程,成功制备了Fe_(2)O_(3)中空纳米纤维材料。通过X射线衍射、扫描电镜和透射电镜表征了中空纤维的物相结构和形貌。作为锂离子负极材料,Fe_(2)O_(3)中空纤维材料的电化学性能通过电池充放电系统和电化学工作站进行了全面的研究。本综合实验设计主要包括静电纺丝、电极制作和扣式电池装配等操作,涵盖了材料的结构、形貌以及电化学性能的分析和评价。这不仅有效解决了本校新增设的新能源材料与器件本科专业配套教学实验匮乏的问题,还能帮助学生深入地了解本专业的研究前沿,激发学习专业知识的热情。Fe_(2)O_(3)hollow nanofibers were prepared via electrospinning technology and subsequent calcination process.The phase and morphology of the hollow nanofibers were analyzed by X-ray diffraction,scanning electron microscopy,and transmission electron microscopy.The lithium storage performance of the Fe_(2)O_(3)hollow nanofibers was comprehensively studied using battery test systems and electrochemical workstations.This experiment primarily encompasses operations,such as electrospinning,preparation of electrode,and coin-cell assembly,alongside the analysis and evaluation for structure,morphology,and performance of active materials.This design effectively addresses the lack of supporting teaching experiments for the newly established undergraduate major in new energy materials and devices,helping students gain a deeper understanding of research frontiers in this field and inspiring their enthusiasm for the professional knowledge.
