Cyclic voltammetry (CV) is one of the most important electrochemical research methods; however, many instrumental analysis textbooks only briefly discuss CV operating principles.The electrode reaction processes are not discussed in-depth; consequently, students can lack the necessary skills to interpret CV curves. This study analyzed the electrode processes to determine the changes in the concentration of electroactive materials at the electrode/interface. Furthermore, the characteristics of the CV curve and the effect of concentration and scanning speed on the CV curve are also described. Finally, the philosophical principles contained in CV are discussed. This study can provide reference information for both peer teaching and student learning.
