How Are Super Capacitors Different

May. 25, 2022

The emergence of electronic products has not only facilitated our lives but also enriched our entertainment methods. Capacitors are widely used in electronic devices. There are ceramic capacitors, film capacitors, electrolytic capacitors, supercapacitors, etc. So what is the difference between super capacitors and ordinary capacitors? This article will give an analysis from three aspects: definition, structure, and working principle.


Definition:

Ordinary capacitors are a static charge storage medium, and this charge may exist for a long time and has a wide range of uses.


Supercapacitor is a new type of energy storage device. It is an electrochemical component between traditional capacitors and rechargeable batteries. No chemical reaction occurs during the energy storage process.


How Are Super Capacitors Different


Construction:


Ordinary capacitors are composed of two parallel metal electrodes that are close but not in contact with a dielectric insulating material in the middle.


A supercapacitor consists of electrodes, an electrolyte (containing electrolyte salts), and a separator (to prevent contact between the positive and negative electrodes).


3. Working principle:


When an ordinary capacitor works, the electric charge will be moved by force in the electric field. When there is a medium between the conductors, it will hinder the movement of the electric charge and cause the electric charge to accumulate on the conductor, resulting in the accumulation and storage of the electric charge.


Supercapacitors realize double-layer charge energy storage by polarizing electrolytes and redox charges. No chemical reaction occurs during the energy storage process, so they can be repeatedly charged and discharged hundreds of thousands of times.


After reading the above content, do you have an idea of the differences between super capacitors and ordinary capacitors? When purchasing capacitors, it is advisable to do some searches to find out if a manufacturer is reliable.
