Furthermore, it was utilized as electro-active materials in supercapacitor to lead students to construct next-generation flexible energy-storage apparatus and study its electrochemical performances in detail. According to the experiment results, this preparation method was simple and the electrochemical performances are excellent. Moreover, the experimental skills such as nonmaterial synthesis, cyclic voltammetry and galvanostatic charge-discharge could also be well trained. In general, this experiment met the demands of research-based experiment, and it helped to improve students’ analysis and problem solving capability.
