Aluminum Electrolytic Capacitors:

Aluminum electrolytic capacitors, or aluminum electrolytic capacitors, are electrochemical capacitors that are defined according to the type of electrolyte used. This type of capacitor has relatively low self-inductance, large capacitance value for given volume, and high voltage and temperature tolerances. The electrolyte in an aluminum electrolytic capacitor serves as an anode. An oxidized-aluminum layer (electrolyte) covers the anode, forming a porous capacitor plates. The second electrical terminal is a cathode, usually a metal with high electrical conductivity, connected to negative polarity. The two terminals are separated by an electrolyte that dissociates into ions, which are attracted to opposite electrode, and provide an electric circuit (capacitance) between them during charge exchange.
