Comprehensive Experimental Design for Preparation and Performance of Fiber-Shaped Supercapacitors
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 increas-ing 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 under-stand the structure and design principles of fiber energy storage devices.This will deepen their understanding and knowledge of electro-chemical 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.
