A double layer (DL, also called an electrical double layer, EDL) is a structure that appears on the surface of an object when it is exposed to a fluid. The object might be a solid particle, a gas bubble, a liquid droplet, or a porous body. The DL refers to two parallel layers of charge surrounding the object Electric double layers form whenever two conducting phases meet at an interface. Generally, one of the phases acquires a positive excess charge on its surface, which is balanced by a countercharge of the same magnitude and opposite sign on the other phase In the electric double layer, the positive (or negative) charge buildup at the interface of the electrode and electrolyte solution is partially neutralized by the gathering of counterions in the solution through the action of Coulomb's force, resulting in a structured electric double layer. The electric double layer consists of two layers

An electric double layer capacitor stores more charge or energy than standard capacitors. This is because the plates used in the capacitor have a larger surface area and a shorter distance between the plates when compared to standard capacitors. Due to the high stored charge, the capacitors are also known as supercapacitors. Supercapacitors consists of two metal plates made of porous material. An electrical double layer exists around each particle. The liquid layer surrounding the particle exists as two parts; an inner region (Stern layer) where the ions are strongly bound and an outer (diffuse) region where they are less firmly associated; Within this diffuse layer is a notional boundary known as the slipping plane, within which the particle acts as a single entity ; The potential. The electric double layer capacitance was numerically predicted for spherical ultramicroelectrodes of various radii in aqueous electrolyte.

The electric double layer (EDL) is fundamental to understanding the properties of charged colloidal systems. The EDL idea was introduced by Gouy, Debye, and Huckel to describe how microions distributed themselves close to a charged surface.
