An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor.
Electrolytic capacitors are known to be sensitive to temperature and frequency variations. In fact, an electrolytic capacitor has several modes and causes of failure. The main reason for temperature dependence is due to the electrolyte and for the frequency it is due to the dielectric oxide .
The electrolyte of the capacitor can be solid, liquid or gel. This electrolyte covers the oxide layer and acts as the cathode. Due to this enlarged anode surface and very thin dielectric oxide layer, electrolytic capacitors can have a high capacitance voltage per unit volume. Hence they can have a high capacitance value.
There are many studies on the failure modes of electrolytic capacitors, and mainly aluminum electrolytic capacitors. Indeed, from the understanding of the mechanisms and failure modes of a capacitor, it is possible to apply a maintenance in order to know the remaining lifetime of the component.
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).
