The cathode foil has a capacitance (Cc) that uses the oxide layer, which formed by the forming voltage or formed naturally during storage (generally 1V or less), as a dielectric. According to the construction of aluminum electrolytic capacitors, Ca and Cc are connected in a series.
If both the anode and cathode foils have an oxide film, the capacitors would be bipolar (non-pola) type capacitor. These technical notes refer to "non-solid" aluminum electrolytic construction in which the electrolytic paper is impregnated with liquid electrolyte.
This cathode foil is provided with a very thin, natural, air-originated oxide layer, which act also as a dielectric. Thus, the capacitor construction forms a series circuit of two capacitors, the capacitance of the anode foil C A and the cathode foil C K.
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. The process develops aluminum oxide (Al203) to form a capacitor dielectric.
The electrolytic capacitor got its name from the electrolyte, the conductive liquid inside the capacitor. As a liquid it can be adapted to the porous structure of the anode and the grown oxide layer with the same shape and form as a "tailor-made" cathode.
Anode and cathode foils interleaved with an electrolytic paper are wound into a cylindrical capacitor element, with leads being connected to both foils. Elements are impregnated with liquid electrolyte. The clearance between the two electrode foils is filled with liquid electrolyte.

As to the basic construction principles of electrolytic capacitors, there are three different types: aluminium, tantalum, and niobium capacitors. Each of these three capacitor families uses non-solid and solid manganese dioxide or solid polymer electrolytes, so a great spread of different combinations of anode material and solid or non-solid electrolytes is available.
