Aluminum electrolytic capacitors are electrochemical energy storage devices that are widely used in the electrical industry. In particular, the EEV-TG1K221M capacitor is an especially popular device, due to its superior performance and diverse applications. The following is an exploration of the working principles and potential applications of aluminum electrolytic capacitors, and specifically the EEV-TG1K221M capacitor.

Composition of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are composed of a three-layer structure, consisting of an anode, a separator, and a cathode. Generally, the anode is aluminum foil covered with a thin oxide film, which serves as a dielectric layer. The separator is a paper or polymer material that is soaked in an electrolyte and is coated with a thin oxide film. The cathode is a metal oxide film, such as manganese dioxide, which is attached to the anode for electron conduction. The terminals of an aluminum electrolytic capacitor are connected to the anode and cathode, respectively.

Working Principle

When an external alternating current is applied, the thin oxide film on the anode will be able to hold a certain amount of electric charge. As more charge is applied, the thin oxide film will eventually reach its saturation point and the excess charge will be distributed onto the cathode through the electrolyte. As the charge accumulates on the cathode, it will form an electric double-layer which will further increase the capacitance of the capacitor. When the current is removed, the charge stored on the cathode will dissipate and the capacitance will drop to its original value.
