An electrode’s potential relative to a specified reference, conventionally tabulated for its reduction half-reaction.
The difference between an applied electrode potential and the relevant equilibrium potential. Increasing its magnitude can drive electron transfer toward a mass-transport limit.

Electrode potential is a measure of the tendency of an electrode to either gain or lose electrons in an electrochemical reaction. It reflects the energetic favorability of the reduction or oxidation process occurring at that electrode. Electrode potential is typically measured in volts (V) and can be defined in relation to a standard reference electrode, most commonly the Standard Hydrogen Electrode (SHE), which is assigned a potential of 0.
