Abstract: Combining material science, basic experimental teaching andcurrent electronchemical research work, flower-like CuO was prepared by a simple chemical water bathe method as a negative electrode material for lithium ion batteries, and material teaching, button cell assembly and ecletrochemical performance test experiments were carried out. Throug the experimental teaching, students can understand the charging and discharging principle of lithium ion batteries, master the packaging process and battery testing methods of lithium ion batteries, deepen the application of basic knowledge of material science in the field of electrochemistry, and improve students’ sense of innovation and self-lerning ability.
