What is a Farad Capacitor? What is the function of Farad capacitor?

Speaking of capacitors , many people know more or less what they are, but when it comes toFarad capacitors may be a little unfamiliar. In fact, in our daily life, farad capacitors are also very common, such as: computer memory backup power supply, solar energy, fast flash charging applications, etc., it can be seen that the effect of farad capacitors is very strong. As one of the widely used components, let's take a look at what is a Farad capacitor and what is the function of a Farad capacitor today.

1. What is a Farad capacitor ?

Farad capacitors, also known as electric double-layer capacitors , gold capacitors , and supercapacitors , are chemical components developed in the 1970s and 1980s. Supercapacitors store energy through polarized electrolytes, but no chemical reaction occurs, and the energy storage process is reversible, which is why supercapacitors can be repeatedly charged and discharged hundreds of thousands of times.

The difference between the amount of Farad capacitors and the general capacitors is the difference in capacity first. The maximum capacity of general capacitors is 10,000 to 40,000 microfarads, and the maximum capacity of supercapacitors can reach thousands of farads, 1 farad = 1 million microfarads, so supercapacitors are also called farad capacitors.

Farad capacitors are classified as electric double-layer capacitors, which are the largest electric double-layer capacitors in the world that have been put into mass production. The basic principle is the same as other types of electric double-layer capacitors, using activated carbon porous electrodes and electrolytes. The composed electric double layer structure obtains a large capacity.

Second, the role of Farad capacitors

Because the Farad capacitor is a new type of energy storage device, it has the characteristics of short charging time, long service life, good temperature characteristics, energy saving and green environmental protection, so the effect of Farad capacitor is very wide.

The role of the Farad capacitor is as follows:

1. The Farad capacitor can store the energy in the separated charge. The larger the area used to store the charge and the denser the separated charge, the higher the capacitance, so it can be used as a capacitor.

2. The area of the Farad capacitor is based on the porous carbon material. The porous structure of the material allows its area to reach 2000m2/g. After some measures, a larger surface area can be achieved. The distance over which the Farad capacitor charge detaches is determined by the size of the electrolyte ions that are attracted to the charged electrode. Farad capacitors can make this distance smaller than what traditional capacitor film materials can accomplish, so farad capacitors have a much larger capacity than ordinary capacitors.

3. Farad capacitors can generate huge electrostatic capacity by virtue of their huge surface area and very small charge separation distance.

In fact, the effect of Farad capacitors is very extensive. It has already been used in various fields in our daily life. Do you want to know more about the fields of practical application of Farad capacitors and the effect of Farad capacitors? Please visit our official website!
