Capacitor aluminum foil film pictures
The cathode foil material uses an aluminum foil that is at least 99% pure and about 15 to 60 µm thick. Because the capacitance is proportional to the surface area of the electrodes, the effective surface area is increased by roughening (etching) the surface of the aluminum foil before growing the dielectric film. - Download [PDF]

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.
Aluminum electrolytic capacitor
OverviewBasic informationMaterialsProductionStylesHistoryElectrical parametersReliability, lifetime and failure modes
Aluminum electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor. A non-solid electrolyte covers the rough surface of the oxide layer, serving in principle as the second electrode (cathode) …

Further, the oxide film, even a "thick" one, is thinner than the thinnest tissue paper. This thin film of aluminum oxide reduces the bulk of the capacitor; but more important, its thinness also increases the capacitance per unit of area. Another advantage of aluminum foil for electrolytic capacitors is that the foil is readily etched.

Aluminum Electrolytic Capacitors
As is the case with all capacitors, an aluminum electrolytic capacitor comprises two electrically con-ductive material layers that are separated by a dielectric layer. One electrode (the anode) is formed by an aluminum foil with an enlarged surface area. The oxide layer (Al2O3) that is built up on this is used as the dielectric.
Capacitor types
The electrodes of film capacitors may be metallized aluminum or zinc, applied on one or both sides of the plastic film, resulting in metallized film capacitors or a separate metallic foil overlying the film, called film/foil capacitors. Metallized film capacitors offer self-healing properties.
