Tafel plots) for one-step symmetric BV kinetics with different values of α or I0; Fig. shows the same data in the resistance notation given by Eq. 10. From the Tafel plots, we observe the familiar behavior of BV kinetics: I0 essentially describes the current above which the kinetics enter the non-linear region, while α describes the rate at which overpotential scales with current (i.e., The resistance versus current plots reveal that Rct is constant and equal to 𝑅 𝑐𝑡 0 within the linear region (i.e., I < I0). However, Rct begins to decrease once the current approaches I0, and Rct decays logarithmically with current within the non-linear region (i.e., I > I0). It is evident that I0 greatly affects both the magnitude of 𝑅 𝑐𝑡 0 and the current dependence of Rct, while α affects only the magnitude of Rct (Fig. ). The current dependence of Rct can be better understood by plotting the normalized charge-transfer resistance (r) versus either current or overpotential (Fig. ).
