6 FAQs about [Capacitor detection aluminum foil principle]

Why is sintered foil used in aluminum electrolytic capacitors?

The sintered foil with 30 vol% starch has potential applications in aluminum electrolytic capacitors due to its high specific capacitance (0.886 μ F/cm 2) and anti-buckling performance (more than 120 times) that meet the requirements for winding. J. Both, The modern era of aluminum electrolytic capacitors.

How are aluminum electrolytic capacitors made?

Aluminum electrolytic capacitors are made by layering the electrolytic paper between the anode and cathode foils, and then coiling the result. The process of preparing an electrode facing the etched anode foil surface is extremely difficult. Therefore, the opposing electrode is created by filling the structure with an electrolyte.

Can powder metallurgy prepare anode foil materials with high specific capacitance?

The specific capacitance of the sintered foils was predicted using the close-packed packing model, which can help establish a powder metallurgy method for preparing anode foil materials with high specific capacitance and anti-buckling performance for aluminum electrolytic capacitors.

What determines the performance of an aluminum electrolytic capacitor?

The grown oxide layer, resulting from the solute and the solvent (electrolyte), greatly controls the performance of the aluminum electrolytic capacitor. The component materials generally used are as shown in Table 2. Topics on principles of ELNA aluminum electrolytic capacitors。

Does porous sintered aluminum foil increase capacitance of anode foil?

In contrast, an aluminum foil with a thickness of 120 μ m, produced using tunnel etching technology, has a lower expansion surface ratio of 65 or below. Therefore, the use of porous sintered foil significantly enhances the specific capacitance of the anode foil.

How does the specific capacitance of a sintered foil change with size?

Typically, the specific capacitance of the sintered foil increases with decreasing the size of the aluminum powder. In contrast, the specific capacitance of the sintered foils increases with an increase in the sphericity and volume fraction of the aluminum powder.
