What is electric double layer capacitor (EDLC)?

Electric double layer capacitor (EDLC) [1, 2] is the electric energy storage system based on charge–discharge process (electrosorption) in an electric double layer on porous electrodes, which are used as memory back-up devices because of their high cycle efficiencies and their long life-cycles. A schematic illustration of EDLC is shown in Fig. 1.

Why do supercapacitors have a higher capacitance?

The thickness of the double layer reflects the electric double layer capacitor (EDLC). The deeper the electric double layer, the higher capacitance behavior is observed. Supercapacitors can be systematized into two major sorts of EDLCs and pseudocapacitors depending on the charge storage mechanism.

What is the capacitance mechanism of electric double layer capacitors?

Binoy K. Saikia The capacitance mechanism of Electric Double Layer Capacitors is similar to that of dielectric capacitors. In conventional capacitors, energy is stored by the accumulation of charges on two parallel metal electrodes which separated by dielectric medium with a potential difference between them.

What is a two terminal supercapacitor?

A two terminal supercapacitor would then be the equivalent of two capacitors in series. Due to the high electrode surface area and thin IHP and OHP, the supercapacitor essentially bridges the energy and power gap between a battery and traditional capacitors as it leverages the basic theory behind capacitors.
