The Working Principle of Supercapacitor

Aug. 06, 2021

     Super capacitor is a kind of physical secondary power supply with super power storage capacity and can provide powerful pulse power. It is developed based on the electrochemical double-layer theory, so it is also called an electric double-layer capacitor. Freshmen who have just entered the industry may have no idea about the working principle of supercapacitors. Hopefully this article will be helpful to those who want to understand the working principle of supercapacitor.


     The basic principle is: when the electrode is charged, the charges on the electrode surface (in its ideal status) will attract the opposite ions in the surrounding electrolyte solution, so that these ions attach to the electrode surface to form an electric double layer, forming an electric double layer capacitor. Due to the small distance between the two charge layers (generally less than 0.5mm), coupled with the use of a special electrode structure, the electrode surface area is increased tens of thousands of times, resulting in a great electric capacity.


     The advent of supercapacitors has achieved a leap in capacitance from microfarad to farad, and has completely changed people's traditional impression of capacitors. At present, supercapacitors have formed a series of products, with a capacitance of 0.5-1000F, a voltage of 12-400V, and a large discharge current of 400-2000A.


     The above content is the working principle of supercapacitors. With the advancement of technology, the application fields of supercapacitors are becoming more and more extensive, and the requirements for the quality of capacitors are also becoming higher. Therefore, it is very important for us to choose a reliable super capacitor manufacturer.
