Redox reactions in batteries with faradaic charge-transfer between an electrolyte and the surface of an electrode were characterized decades ago. Redox reactions Differences Rechargeable batteries Development of the electrochemical components see Supercapacitors.Development of the double layer and pseudocapacitance model see Double layer (interfacial).The amount of electric charge stored in a pseudocapacitance is linearly proportional to the applied voltage. Pseudocapacitance may contribute more capacitance than double-layer capacitance for the same surface area by 100x. The amount of pseudocapacitance depends on the surface area, material and structure of the electrodes. Pseudocapacitance and double-layer capacitance both contribute inseparably to the total capacitance value. The adsorbed ion has no chemical reaction with the atoms of the electrode (no chemical bonds arise ) since only a charge-transfer takes place.įaradaic pseudocapacitance only occurs together with static double-layer capacitance.

One electron per charge unit is involved. Pseudocapacitance is accompanied by an electron charge-transfer between electrolyte and electrode coming from a de-solvated and adsorbed ion. This faradaic charge transfer originates by a very fast sequence of reversible faradaic redox, electrosorption or intercalation processes on the surface of suitable electrodes. Pseudocapacitance is the electrochemical storage of electricity in an electrochemical capacitor ( Pseudocapacitor).

Simplified view of a double-layer with specifically adsorbed ions which have submitted their charge to the electrode to explain the faradaic charge-transfer of the pseudocapacitance.
