MnO₂/碳纳米管/石墨烯/泡沫镍复合材料制备及储锂性能评价综合实验设计

In view of practical application in lithium ion battery anode materials, a comprehensive experiment on the preparation and lithium storage properties evaluation of MnO₂/carbon nanotubes/graphene/nickel foam is designed. Firstly, carbon substrate is prepared by chemical vapor deposition, and then manganese dioxide is deposited by hydrothermal reaction to prepare self-assembled electrode. The structure, micro morphology and lithium storage properties are characterized and evaluated by X-ray diffraction, scanning electron microscopy, nitrogen adsorption desorption and electrochemical methods. The experiment involves multiple practical links, such as preparation of nanomaterials, microstructural characterization, battery assembly process, evaluation of energy storage performance, which covers electrochemistry, solid state physics, materials science and other disciplines, taking the hot application problems as the starting point, combined with the actual scientific research achievements, it can improve the students’ practical ability of scientific research and the ability to solve practical problems in multiple dimensions, and stimulate their enthusiasm for scientific research.
