Working Principle of Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor’s structure is composed of two electrodes and a dielectric formed by an electrochemical reaction. The dielectric layer consists of a thin film of aluminum oxide, which anions form when the metal aluminum is exposed to an electrolyte solution. The positive electrode is formed by partial current collector, the negative electrode is usually referred to as the “backplate”, and the liquid electrolyte is sandwiched between the two. When charging, electrons accumulate on the positive electrode, while anions are discharged from the negative electrode, forming an electric field between them.

When this kind of capacitor is discharged, the electrons left on the positive electrode are removed and the anions enter back into the electrolyte. This causes a flow of current from the positive to the negative electrode. The dielectric is the resistance to the flow of current, which makes capacitor act like a resistor. As such, it stores energy, while also allowing carbon and other substances to pass through, making aluminum electrolytic capacitors very efficient components.

Mal202126102E3 is a miniature, solid aluminum electrolytic capacitor that has the ability to store large amounts of energy in a small package.
