What is a supercapacitor and what are the functions of a supercapacitor

With the advancement of science and technology, modern R&D and production pay more and more attention to high efficiency and low energy consumption, and the world is advocating green environmental protection. As we know, a lot of power consumption is inevitably accompanied by waste generation that pollutes the environment. Thus, supercapacitors came into being. Many people are not very familiar with capacitors , let aloneSupercapacitors and the role of supercapacitors. So today we will talk about what is a supercapacitor and what is the role of a supercapacitor.

1. What is a super capacitor

Supercapacitors, also known as electrochemical capacitors , are electrochemical components developed in the 1970s and 1980s that use polarized electrolytes to store energy. The "super" of supercapacitors is compared with ordinary capacitors.

Supercapacitors are also called Farad capacitors and gold capacitors , which have a large Farad-level capacitance. The fundamental type of supercapacitor is a capacitor made by the principle of electric double layer, which is the most important type of supercapacitor. It is different from general capacitors. Generally, capacitors can obtain capacitance by polarization of electrolyte, while electric double-layer capacitors obtain capacity by the positive and negative electric double layers existing at the interface between solid and solid, or between liquid and solid.

The capacitance of an electric double-layer capacitor depends on the interfacial double-layer charge, which is different from the polarization charge of the electrolyte. Therefore, the working principle of electric double-layer capacitors is completely different from the electrolytic capacitors that use oxide dielectrics as power storage materials , and general capacitors such as ceramic capacitors. New electronic components between capacitors and batteries.

2. What is the role of supercapacitors?

Because supercapacitor is a new type of energy storage device, it has the characteristics of short charging time, long service life, good temperature characteristics, power saving and environmental protection.

The role of supercapacitors is as follows:

1. Supercapacitors can store the energy in the separated charges. The larger the area used to store the charges and the denser the separated charges, the greater the capacitance.

2. The area of the supercapacitor 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 separation of supercapacitor charges is determined by the size of the electrolyte ions attracted to the charged electrodes. Supercapacitors enable this spacing to be smaller than can be accomplished with conventional capacitor film materials.

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

The above is only the main part of the role of supercapacitors, and the role of supercapacitors is far beyond our imagination.

In fact, there are many areas where super capacitors are used around us now , and the most common ones are cars that use super capacitors. The role of supercapacitors is actually very extensive, and it can be used in various places in our daily life.
