Customer ServiceAn 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.
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).
Note: At temperatures of up to 85°C, medium to high voltage capacitors use ethylene glycol (EG) or boric acid as the electrolytes. The symbol is shown in the figure below. One straight line and one curved line, or two parallel straight lines, are used to denote it.
The electrolyte material enables the electrolytic capacitor to produce large capacitances. The electrolyte used in these capacitors is a liquid or gel-like substance that works as a dielectric material. It enables the electrolytic capacitor to have a large capacitance in its compact size.
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.
Like other conventional capacitors, electrolytic capacitors store the electric energy statically by charge separation in an electric field in the dielectric oxide layer between two electrodes. The non-solid or solid electrolyte in principle is the cathode, which thus forms the second electrode of the capacitor.
