Aluminium electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminium foil with an etched surface. The aluminum forms a very thin insulating layer of aluminium oxide by anodization that acts as the dielectric of the capacitor. A non-solid electrolyte covers.

Aluminum electrolytic capacitors, often called electrolytic capacitors, are usually selected because they offer a relatively large capacitance for a relatively small physical size. Aluminum electrolytic capacitors tend to be readily available, and with high voltage values (on the order of 700 V).
The basic material of the anode for aluminum electrolytic capacitors is a foil with a thickness of ~ 20–100 μm made of aluminum with a high purity of at least 99.99%. This is etched (roughened) in an electrochemical process to increase the effective electrode surface.
The essential property of a capacitor is to store electrical charge. The amount of electrical charge (Q) in the capacitor (C) is proportional to the applied voltage (U). d = thickness of the dielectric (oxide layer in aluminum capacitors) (m). Characteristics of aluminum capacitors vary with temperature, time and applied voltage.
One reason could be the following: During the operation of an aluminum electrolytic capacitor with non-solid electrolyte, there is a small quantity of hydrogen developed in the component. Under nor-mal conditions, this gas permeates easily out of the capacitor.
The oxide layer of aluminum electrolytic capacitors may deteriorate when they are stored without an externally applied voltage, especially at higher temperatures. Since there is no leakage current to transport oxygen ions to the anode in this case, the oxide layer is not regenerated.
This is why most aluminum capacitors are polarized; the application of voltage with the wrong polarity causes rapid erosion & thinning of the dielectric, resulting in high leakage current and excessive internal heating.
