The supercapacitor stores energy in the separated charge, and the larger the area for storing the charge, the denser the separated charge, and the larger the capacitance.
The area of a conventional capacitor is the flat area of the conductor. In order to obtain a large capacity, the conductor material is rolled up very long, and sometimes a special tissue structure is used to increase its surface area. A conventional capacitor is a two-pole plate that is separated by an insulating material, typically a plastic film, paper, etc., which are usually required to be as thin as possible.
The area of the supercapacitor is based on a porous carbon material, the porous structure of which allows for an area of up to 2000 m2/g, and a larger surface area can be achieved by some measures. The distance separating the supercapacitor charge is determined by the size of the electrolyte ions that are attracted to the charged electrode. This distance (<10 & Aring;) and conventional capacitor film materials can achieve a smaller distance. This large surface area combined with a very small charge separation distance makes supercapacitors have an incredibly large electrostatic capacity compared to conventional capacitors, which is also the "super". 


advantage
The capacitance of the Farah level is reached in a small volume; no special charging circuit and control discharge circuit are required; compared with the battery, overcharge and overdischarge do not have a negative impact on its life; from the environmental point of view, it is a kind Green energy; supercapacitors can be soldered, so there are no problems such as weak battery contact; 


Disadvantage
If it is used improperly, it will cause electrolyte leakage and the like; compared with aluminum electrolytic capacitors, it has a large internal resistance and thus cannot be used in an AC circuit;
