Working Principle

The working principle of the aluminum electrolytic capacitor is based on the physical phenomena of electrolysis and Faraday\'s law. It utilizes two aluminum electrodes, each of which is separated by a thin diaphragm of an electrolyte. When a voltage is applied to the aluminum electrodes, current electrons transfer between them, forming an electric double layer at the interface between the electrodes. This electric double layer acts as a barrier for the current electrons, allowing the capacitor to store electrical energy in the form of an electrostatic field.

At the same time, the electrolyte in the capacitor will be ionized due to current flow, which results in the formation of a thin oxide layer on the surface of the aluminum electrodes. This layer acts as a dielectric medium that increases the capacitance of the capacitor. With the increase of the electrolyte’s applied voltage, the electric field increases and the capacitance increases as well.
