► Voltammetry under Butler–Volmer and Marcus–Hush electrode kinetic models are compared. ► Notable discrepancies are found for slow kinetics, short pulses and microelectrodes. ► These differences can affect significantly the extraction of kinetic parameters. ► Striking phenomena predicted with Butle...
