摘　　要：为了实现前沿的科学研究与课堂实验教学的有效融合,设计了一例综合实验——原位合成有机碳硫硒正极材料用于钠离子电池。通过热处理工艺,将原料SeS2在加热过程中转化为与碳化聚丙烯腈(PAN)结合的小分子基团,从而原位合成了一种新型有机碳硫硒复合材料。高导电性的有机碳基质能够有效促进电子和离子的传输,并显著提升SeS2的电化学活性。因此,该有机碳硫硒正极材料在钠离子电池中显示出良好的电化学特性。通过这一综合实验,学生能够将理论知识与实际应用紧密结合,不仅有效激发了他们对理论学习的兴趣,还帮助其深入理解材料专业的基础知识。在独立完成实验的各个环节中,学生分析与解决问题的能力得到了有效提升,进而实现科研与教学的相互促进。To effectively integrate cutting-edge scientific research with laboratory teaching,a comprehensive experiment was designed-in situ synthesis of organic carbon-sulfur-selenium composite for sodium-ion battery.Through the heat treatment process,the precursor SeS_(2) is converted into small molecular groups that bond with carbonized polyacrylonitrile(PAN),resulting in the formation of a novel organic carbon-sulfur-selenium composite material.The highly conductive organic carbon matrix efficiently facilitates the electron/ion transport,significantly enhancing the electrochemical activity of the SeS_(2).Consequently,this organic carbon-sulfur-selenium composite material demonstrates excellent electrochemical performance in sodium-ion battery.Through this comprehensive experiment,students are able to closely connect theoretical knowledge with practical applications,effectively stimulating their interest in theoretical learning and helping them gain a deeper understanding of fundamental knowledge in materials science.By independently completing each stage of the experiment,their problem-solving and analytical skills are enhanced,thereby cultivating a mutually reinforcing relationship between research and teaching.
