How do electrolytic capacitors work?
Principle of electrolytic capacitors Electrolytic capacitors consist of two electrodes (anode and cathode), a film oxide layer acting as a dielectric and an electrolyte. The electrolyte brings the negative potential of the cathode closer to the dielectric via ionic transport in the electrolyte (see Fig. 2).

The separator is then sandwiched between anodic and cathodic foils. A dielectric is also used to prevent direct contact of the foils with the electrolyte.
What are the mechanisms and failure modes of an electrolytic capacitor?
Mechanisms and failure modes according to the stress in an electrolytic capacitor. A normal use of the capacitor leads to the evaporation of the electrolyte and the repair of the oxide layer. These are two causes of electrolyte disappearance, which is the main cause of capacitor degradation under normal conditions.
How does electrolyte affect the capacitance of a capacitor?
The electrolyte must adhere to the whole surface of the anode and cathode foils to have a higher capacitance. It can also repair defects in the anode oxide film as seen before. The nature of the electrolyte influences the temperature and frequency characteristics response of the capacitor (Fig. 4. 5).
What is an electrolytic capacitor?
An electrolytic capacitor is a capacitor that to produce a higher capacitance than other capacitor types employs an electrolyte. A liquid or gel that has a lot of ions in it is an electrolyte. Since almost all electrolytic capacitors are polarised, the positive terminal’s voltage must always be higher than the negative terminal’s voltage.
What is the operating temperature of an electrolytic capacitor?
This type of capacitor has an operating temperature of up to 150 °C in some cases, allowing a wide range of operating temperatures. Moreover, compared to other electrolytic capacitors, they are less expensive not only because of the materials used but also because of the manufacturing process. They offer good stability and a long service life.
