Exploring Impact of Various Operating Parameters on the Specific Capacitance at the Glassy Carbon/H2SO4 Interface: A Comparative Analysis Using Electrochemical Characterization

“…However, the behavior of the different contributions is similar, the specific capacitance increases as the scan rates decrease. At lower scan rates, ions have more time to diffuse through the electrode bulk, resulting in an increase capacitance [47] . Regardless of all scan rates, diffusion plays the most important role, this result indicates that the storage capacity in this specific system is primarily influenced by diffusion processes rather than the creation of an electrical double layer.…”

[47] Regardless of all scan rates, diffusion plays the most important role, this result indicates that the storage capacity in this specific system is primarily influenced by diffusion processes rather than the creation of an electrical double layer. Figure 10 shows an example of the comparison between experimental cyclic voltammetry (CV) data and synthetic voltammograms obtained from SPECS analysis using different scan rates of (a) 0.001, (b) 0.005 and (c) 0.01 V/s.…”
