These two layers, electrons on the electrode and ions in the electrolyte, are typically separated by a single layer of solvent molecules that adhere to the surface of the electrode and act like a dielectric in a conventional capacitor. The amount of charge stored in double-layer capacitor depends on the applied voltage.

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.
Double-layer capacitance is the important characteristic of the electrical double layer which appears at the interface between a surface and a fluid (for example, between a conductive electrode and an adjacent liquid electrolyte).
Because an electrochemical capacitor is composed out of two electrodes, electric charge in the Helmholtz layer at one electrode is mirrored (with opposite polarity) in the second Helmholtz layer at the second electrode. Therefore, the total capacitance value of a double-layer capacitor is the result of two capacitors connected in series.
When the double layer capacitance idea is used to create a device, they are sometimes called "ultracapacitors" because they store energy by separating the charges (like a capacitor but capable of storing more energy), instead of using a chemical reaction to store electricity.
