Ideally polarizable electrode

Ideally polarizable electrode (also ideal polarizable electrode or ideally polarized electrode), in electrochemistry, is an electrode characterized by an absence of net current between the two sides of the electrical double layer, i.e., no faradic current between the electrode surface and the electrolyte. Any transient current that may be flowing is considered non-faradaic. Ideally polarizable electrode (also ideal polarizable electrode or ideally polarized electrode), in electrochemistry, is an electrode characterized by an absence of net current between the two sides of the electrical double layer, i.e., no faradic current between the electrode surface and the electrolyte. Any transient current that may be flowing is considered non-faradaic. Ideally polarizable electrode is contrasted with ideally non-polarizable electrode, for which a faradic current can freely pass (without polarization). A polarizable electrode ideally has no DC current flow between the electrode and the surrounding electrolyte. It shows a very large change in potential upon passage of small current. The electrode/electrolyte interface behaves like a capacitor.
