3. Capacitive phenomena at electrochemical interfaces
The existence of capacitive phenomena in an electrochemical cell is particularly responsible for the observation of a current in circumstances where no electrochemical reaction is taking place. The origin of this current, which differs from the electrolysis current (which is also called faradic, because the process giving rise to it obeys Faraday's law), is the electrical behavior of the electrode/electrolyte interface, where charge accumulates on either side of the interface, like a charged capacitor.
3.1 Electrical double layer near the electrochemical interface
The accumulation of electric charge (non-transferable across the interface, in the absence of any electrochemical process) on either side of an interface is the consequence of the existence, in the...
