Aluminium foil for electrolytic capacitor

Aluminum foil is one of the components of power capacitor equipment. The addition of aluminum foil material can not only improve the quality of the capacitor, but also increase the voltage resistance of the capacitor while ensuring the performance and life of the capacitor. Next, let’s talk about the role of aluminum foil in power capacitors to some companies that don’t know the situation.

The aluminum foil in the capacitor is the key basic raw material of the aluminum electrolytic capacitor. It is the part with the highest technical content and added value in the entire aluminium foil for electrolytic capacitor. The quality of aluminum foil directly affects the quality of its downstream products, aluminum electrolytic capacitors, and in turn affects the quality of the final product.

With the advancement of modern science and technology and the continuous improvement of capacitor performance, aluminum electrolytic capacitors have been widely used in consumer electronics, communication products, computers and peripheral products, new energy, automation control, automobile industry, optoelectronic products, high-speed railway and aviation, and military equipment.

In electrolytic capacitors, it is customary to call the negative electrode foil cathode foil. Since the oxide film on the surface of the cathode foil is very thin, increasing the surface area of the cathode foil has little impact on high-voltage capacitors, but it has a greater impact on low-voltage capacitors.

The demand for electrolytic capacitors is strong and the quality requirements are high. During the production process, the surface quality, temperature, grain structure, composition, etc. of the negative electrode foil should be strictly controlled to ensure excellent product performance.

Why use aluminum foil for electrolytic capacitor

    • 1. Aluminum foil in capacitors can increase the capacitance of the capacitor, thereby improving the performance of the capacitor. Aluminum foil is a conductive material that is very helpful for electric field uniformity in capacitors. It can effectively improve the efficiency and stability of the capacitor and ensure that the capacitor can work normally under voltage changes or frequency changes.
    • 2. Aluminum foil in capacitors can also enhance the voltage resistance of the capacitor. Aluminum foil can accept the electric field distributed on the surface of the capacitor, and its good conductivity can effectively disperse the electric field inside the capacitor, thereby reducing the voltage concentration inside the capacitor. Therefore, aluminum foil greatly improves the voltage resistance of the capacitor.
    • 3. Aluminum foil can also ensure the life and performance of capacitors. Aluminum foil has been tested in the high-temperature and high-pressure environment inside the capacitor. It not only has high corrosion resistance, but also has a very stable structure. Therefore, the aluminum foil material has a long service life in the capacitor and can greatly extend the service life of the capacitor.

Advantages of Aluminium foil for electrolytic capacitor

Compared with other types of capacitors, aluminum electrolytic capacitors have the advantages of large unit volume capacity, large rated capacity, high working power plant strength, self-healing effect, and controllable dielectric layer thickness. Therefore, they are widely used in basic components of the electronics industry. is being manufactured and has been recognized by the industry.

First of all, aluminum electrolytic capacitors have a large capacitance per unit volume. Compared with other types of capacitors, the capacity per unit volume may be more than ten to dozens of times, and the electrolyte thickness of aluminum electrolytic capacitors is also tens to hundreds of times that of other capacitors. times.

Secondly, aluminum electrolytic capacitors have a large rated capacity. Due to the large thickness of the oxide film of aluminum electrolytic capacitors, it is easy to expand the area. The rated capacitance of the electrolytic capacitor can be increased according to product manufacturing requirements.

Finally, electrolytic capacitors also have a self-healing effect. If the capacitor electrolyte is damaged, the acid ions in the electrolyte can block the damaged location in a short time, thereby restoring the electrolytic capacitor to its normal state. This increases the risk to a certain extent. Application range of electrolytic capacitors.

It is precisely these advantages that make electrolytic capacitors stand out from the competition with other capacitors. They are widely used in the fields of automotive electronics and frequency conversion technology, and their market share is also increasing year by year.

The structure of electrolytic capacitor

Modern electronic equipment is updated very quickly. Each change places higher requirements on the performance of electrolytic capacitors. In order to meet the needs of the development of the electronics industry, electrolytic capacitors must ensure the bending strength of corrosion filters. , so that the specific capacity of electrolytic capacitors continues to increase, which requires electrolytic capacitors to be improved in the direction of specific capacity and small volume.

Basic Model Of Element

First of all, researchers should have a clear understanding of the structure of aluminum electrolytic capacitors. The structure of electrolytic capacitors consists of two parts. The first part is the aluminum shell and the sealant cover. This is the external component of the electrolytic capacitor, usually made of anode aluminum foil. It is wound with the cathode aluminum foil. There is a layer of aluminum oxide film on the surface of the anode aluminum foil, which plays a role in withstanding voltage. Therefore, the external structure of the electrolytic capacitor determines the life and capacitance of the electrolytic capacitor.

Electrolytic capacitor aluminum foil corrosion expansion

The aluminum foil of electrolytic capacitors mainly expands the effective surface area through the corrosion process, thus increasing the capacitance volume of electrolytic capacitors. The specific volume of electrolytic capacitors is affected by the composition of the aluminum-based material, the state of the aluminum-based material, and the corrosion process.

Therefore, in order to increase the effective surface area of the electrolytic capacitor, relevant staff need to conduct in-depth research on the relationship between the aluminum foil expansion of the electrolytic capacitor and the corrosion process, and clarify the corrosion process. The influence on the expansion of aluminum foil of electrolytic capacitors.
