Electrolytic capacitor is a type of capacitor that uses an electrolyte (a conductive liquid or gel) to achieve a very high capacitance in a relatively small size. It's one of the most widely used types of capacitors in electronics, especially for power supply filtering, decoupling, and energy storage.
Capacitor stores electrical energy in an electric field between two conductive plates. In an electrolytic capacitor, one of those plates is replaced by a thin layer of oxide that acts as the dielectric (the insulating layer), and the other "plate" is a liquid or gel electrolyte that connects to a metal electrode.
