What Does Double Layer Capacitance Mean?
Double layer capacitance is a way to store an electrical charge using an electrode, having a double layer, immersed in an electrolyte. These two layers consist of oppositely charged ions. They are insulated by a thin layer that sticks to the electrode's surface.
Double layer capacitance is used quite frequently in the modern era; super capacitors often use double layer capacitance as a means to achieve their high capacities.
