An electrolytic capacitor is a type of polarized capacitor that uses a wet electrolytic solution and an oxide film to store electrical charge. An example is the aluminum electrolytic capacitor which contains two closely spaced spooled strips of aluminum foil for the positive anode and negative cathode.

Aluminum electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor. A non-solid electrolyte covers the rough surface of the oxide layer, serving in principle as the second electrode (cathode) …
