The Principle of Supercapacitor

- Aug 13, 2018-

The basic principle of a supercapacitor is a new type of electronic component that uses an interface electric double layer formed between an electrode and an electrolyte to store energy. When the electrode is in contact with the electrolyte, due to Coulomb force, intermolecular force or interatomic force, a stable, oppositely signed double layer charge is formed at the solid-liquid interface, which is called an interface electric double layer. The tantalum capacitor, also known as the Faraday quasi-capacitor, is a two-dimensional or quasi-two-dimensional space in the surface or bulk of the electrode. The electroactive material undergoes under potential deposition and undergoes highly reversible chemisorption/desorption or oxidation/reduction reactions. A capacitance is generated which is related to the electrode charging potential.
