Abstract: New energy and new materials is one of the key points of chemistry. In order to allow students to learn related knowledge better, considering the professional content of applied chemistry and material chemistry, preparation and lithium storage performance of vanadium disulfid-biomass derived N-doped carbon nanocomposite was simplified to comprehensive chemical experiment. Heat treatment method is adopted to prepare porous vanadium disulfide nanocomposite. The lithium storage performance of this composite is studied. The experiment including fundamental chemistry and experiment techniques is helpful for students to reinforce the knowledge and improve their experimental skills. At the same time, this experiment which involves the frontier research of new materials and new energy can cultivates students’ scientific research capability and lay a good foundation for students follow-up.
