摘　　要：基于过渡金属碳化物/氮化物(MXene)纤维的制备及其应用于柔性超级电容器的创新性成果,设计了创新综合实验。以MXene纤维为负极,MXene/聚苯胺(PANI)纤维为正极,通过非对称电极结构配置提升电容器电压窗口,进而提升器件的能量密度,解决了MXene基电极阳极氧化造成的器件电势窗窄的问题。通过对纤维电极的微观结构表征、非对称纤维超级电容器电化学性能探究和可穿戴储能应用展示,使学生直观并且深入感受到纤维储能器件的结构和设计原则,加深对电化学储能机制的理解和认识,有效促进学生的学习主动性,增强学生的创新思维、能力和实践技巧,培养学生追求科学真理的热情。The innovative comprehensive experiment is designed based on the preparation of transition metal carbide/nitride(MXene)fibers and their application in flexible supercapacitors.Using MXene fibers as the negative electrode and MXene/polyaniline(PANI)fibers as the positive electrode,an asymmetric electrode structure is configured to enhance the capacitor voltage window,thereby increasing the device s energy density.This approach addresses the issue of narrow potential windows caused by anodic oxidation of MXene-based electrodes.Through the microstructural characterization of fiber electrodes,exploration of the electrochemical performance of asymmetric fiber supercapacitors,and demonstration of wearable energy storage applications,students can intuitively and deeply understand the structure and design principles of fiber energy storage devices.This will deepen their understanding and knowledge of electrochemical energy storage mechanisms,effectively promote their learning initiative,enhance their innovative thinking,abilities,as well as practical skills,and cultivate their passion for pursuing scientific truth.
