An aluminum electrolytic capacitor consists of two
electrically conductive aluminum layers, separated by a
dielectric layer. One of the electrodes (the aluminum foil
called anode) undergoes a Process called ‘forming’, by
which a dielectric layer of aluminum oxide (Al2O3) is
electrochemically coated on it. The other electrode is a
conductive liquid, called the electrolyte. The second
aluminum foil, the cathode, acts as a large surfaced
contact area for passing current to the electrolyte.
