摘要
结合材料相关专业的实践教学目标及学科前沿方向,设计了“锌离子电池负极材料的界面改性及性能表征”综合性实验。以硅烷偶联剂KH570改性锌箔表面,并与丙烯酰胺原位聚合,构筑出聚丙烯酰胺电解质/锌负极一体化结构。在此基础上,组装成锌离子电池并测试其电化学性能,重点探讨了界面改性对降低锌电极与电解质界面电阻的影响。实验内容体现了多学科的交叉融合,具有前沿性和开放性,有利于激发学生的科研兴趣,提升学生的创新思维和综合实验技能。
Combined with the practical teaching objectives and cutting-edge direction of materials related majors,a comprehensive experiment of“interface modification and performance characterization of negative electrode materials for zinc ion batteries”was designed.The surface of zinc foil was modified with silane coupling agent KH570 and polymerized with acrylamide in situ to construct the integrated structure of polyacrylamide electrolyte/zinc anode.On this basis,the zinc ion battery was assembled and its electrochemical performance was tested.The effect of interface modification on reducing the interfacial resistance between zinc electrode and electrolyte was discussed.The experimental content reflected the cross integration of multiple disciplines,was cutting-edge and open,and conducive to stimulate students'interest in scientific research and improve students'innovative thinking and comprehensive experimental skills.
