The cathode is typically a carbon-based layer that is coated on the dielectric layer. This layer in the electrolytic capacitor behaves as the second conductive layer. It is connected to the negative terminal of the capacitor. Other components are also present in the construction of the electrolytic capacitor:
Anode acts as the positive terminal of the capacitor. The dielectric material in an electrolytic capacitor is made up of an oxide layer present on the anode layer. This oxide layer behaves as an insulating material between the anode and cathode. Normally, the dielectric forms when we apply voltage at the anode in the presence of an electrolyte.
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.
The cathode in a wet Aluminum electrolytic capacitor The cathode consists of an Al foil that formerly was plain but now has a certain degree of etching and subsequent surface magnification.
Between the anode and the cathode there is a conductive medium in liquid or solid form called an electrolyte and that in practice serves as part of the cathode. The capacitors derive their name from the electrolyte and are in the everyday language called electrolytics. Sometimes tantalum electrolytics are abbreviated tantalums.
In aluminum electrolytic capacitor, the anode (+) and cathode (-) are constructed using pure aluminum foil. The anode aluminum foil is coated with a thin layer of insulating aluminum oxide (aluminum element with oxygen element). This insulating aluminum foil acts as dielectric of the electrolytic capacitor which blocks electric current flow.
