Definition

Under equilibrium conditions, a bulk electrolyte is an electroneutral, isotropic, and homogeneous solution, and there are no electric fields along any preferential direction. However, at the frontier with another material with mobile free charges (ions or electrons) and a different chemical potential – e.g., the electrode – some anisotropy in the forces experienced by the particles arises, and charge redistribution occurs. Although the interfacial region remains overall neutral, either side of the boundary becomes charged to an equal and opposite extent, forming the so-called electrical double layer or electrified interface. This gives rise to a potential difference across the interface. This potential...
