In academic terms, it is called an electrochemical capacitor compared to the existing electrostatic or electrolytic capacitor. Super capacitors are the capacitors with very high capacitance, also called ultra capacitors, as it has ultra-capacitance. In general, since the charge capacity accumulated in the capacitor is very small, a unit of μF or pF is used, with the developing EDLC technology, SuperCapacitor capacitance is used as the units of F. The unit representing the capacitance of the capacitor is used as the Farad (F). If these research and development is completed, it is expected to increase the capacity of the capacitor. In addition, developing EDLC technology with high power and high energy density is conducted. Recently, researches for applying nanostructures to capacitors have been conducted, and efforts have been made to apply carbon nanotubes as ionic states of liquids having polarity at the interface between a conductive solid electrode and an electrolyte. At this time, various kinds of capacitors can be manufactured according to the material of the insulator, and there are also capacitors which use air as a dielectric without inserting anything. The capacitor is manufactured by putting an insulator between two electrode plates. In the case of alternating current, unlike direct current, the alternating current has the effect of continuously changing the anode and the cathode polarities. By using this function that cannot pass DC, it is used as a DC blocking device in electronic circuits. In addition to collecting electric charges and storing electrical energy, capacitors have a function of instantaneous current flowing through the capacitor when a DC voltage is applied to the capacitor. At this time, a current flows during the storage of the charge, but no current flows in the stored state. 1, electric charges are collected and stored at each electrode. When the DC voltage consisting of Anode and Cathode flows to two electrodes in the structure of Fig.
