By RP Deshpande 20 April 2024. The word ''Pseudo'' is derived from Greek ''pseuds'', meaning ''false'' or ''lying''. Pseudocapacitor is not strictly a capacitor, but looks and behaves like one. It does not work on pure electrostatic process like that in EDLC, but also additionally involves fast and reversible electrochemical process ...

Pseudocapacitance is the electrochemical storage of electricity in an electrochemical capacitor known as a pseudocapacitor. This faradaic charge transfer originates by a very fast sequence of reversible faradaic redox, electrosorption or intercalation processes on the surface of suitable electrodes.
