The mathematics of the BV equation can be greatly simplified if the kinetics are assumed to be symmetric between the anodic and cathodic directions . As will be discussed in detail later (Section 4.2), the experimental methods can also be simplified, and the accuracy of the experimental data can be ensured, by conducting electrochemical kinetic measurements in symmetric cells. In this case, even if the interfacial kinetics of the AM are asymmetric (e.g., αa ≠ αc), the measured voltage versus current data of the symmetric cell are necessarily symmetric:
