Basic construction of aluminum electrolytic capacitor is shown in Fig. 1. Aluminum electrolytic capacitors consist of anode aluminum foil formed with aluminum oxide film on the surface to function as the dielectric. The cathode aluminum foil functions as a collector, and the liquid electrolyte functions as the real cathode.
The shortcomings of aluminum capacitors are mostly related to the volatility of liquid electrolytes. The chemically reactive nature of the materials used in aluminum capacitors is problematic on two points: the dielectric layer’s stability and the device’s long-term mechanical integrity.
When charged aluminum electrolytic capacitor is discharged by shorting the terminals and left open for a while, the voltage between terminals of the capacitor rises again. This increased voltage is called “regeneration voltage”. The mechanism of this phenomenon is explained as follows.
Dielectric of an aluminum electrolytic capacitor is an oxide film formed on surface of aluminum foil by forming process. When voltage is applied to the dielectric, polarization occurs due to dielectric effect. The polarization does not immediately respond to the electrical field and may delay by the elastic viscosity of the molecules.
To obtain higher capacitance, surface area of aluminum foil for electrolytic capacitor increases through the etching process. During the etching process, a DC or AC current is applied to the aluminum foil. This is done in a chloride solution to assist to dissolve the surface.
A 0.05~0.11 mm thick anode foil and a 0.02~0.05 mm thick cathode foil are continuously etched electrochemically in a chloride solution with an AC or DC current. This enlarges the effective surface area of the aluminum foils to attain smaller capacitor sizes.

Manufacturing Process: The production process starts with mother rolls. First, the etched, roughened and pre-formed anode foil on the mother roll as well as the spacer paper and the cathode foil are cut to the required width.
During this process, an inner terminal (called a tab) is attached to each of the aluminum foils. The roll made at this process is called a capacitor element. This is a process for impregnating the element with electrolyte as a true cathode. The electrolyte also functions to …

Aluminum electrolytic capacitors consist of anode aluminum foil formed with aluminum oxide film on the surface to function as the dielectric. The cathode aluminum foil functions as a collector, and the liquid electrolyte functions as the real cathode. The electrolyte is impregnated onto a separator (spacer) paper between both foils.

The electrolyte in the capacitor is not directly poured into the capacitor and soaks the aluminum foil in a liquid state, but is laminated with the aluminum foil through the electrolytic paper that has absorbed the electrolyte. Among them, the selection of electrolytic paper and ordinary paper are somewhat different in their formulations. They are microporous. …
The capacitor production process includes cutting, winding, impregnation, assembly, aging, sealing, printing, casing, measurement, packaging, inspection and other processes.
No headers. Aluminum is easily oxidized, and so its ore, Al 2 O 3, is difficult to reduce fact water is reduced rather than Al 3 + (aq), and so electrolysis must be carried out in a molten salt. Even this is difficult because the melting point of Al 2 O 3 is above 2000°C—a temperature which is very difficult to maintain.. The first successful method for reducing Al 2 O 3 is the one still ...
