A supercapacitor is a new type of energy storage device between a conventional capacitor and a rechargeable battery. It has both the characteristics of rapid charge and discharge of the capacitor and the energy storage characteristics of the battery.
 

Principle editing
A supercapacitor is a new type of component that stores energy through a two-layer interface formed between an electrode and an electrolyte. When the electrode is in contact with the electrolyte, due to the effects of Coulomb force, intermolecular force and interatomic force, the solid-liquid interface exhibits a stable and oppositely-signed double-layer charge, which is called an interface double layer. The electric double layer supercapacitor is regarded as two inactive porous plates suspended in an electrolyte, and the voltage is applied to two plates. The potential applied to the positive electrode plate attracts negative ions in the electrolyte, and the negative electrode plate attracts positive ions, thereby forming an electric double layer capacitor on the surface of the two electrodes. Electric double layer capacitors can be classified into carbon electrode double layer super capacitors, metal oxide electrode super capacitors and organic polymer electrode super capacitors depending on the electrode material. 


Handling Precautions and Guidelines
1. Polarity and voltage of supercapacitor
(1) Supercapacitor have polarities
Do not apply a reverse or AC voltage. If a reversed voltage is applied to a capacitor for a long period of time, then its life will be reduced and critical failures such as electrolyte leakage may occur. 
(2) Do not apply an over-voltage (a voltage exceeding the rated voltage )
If voltage exceeding the rating is applied to the capcacitor for a long time, then its life will be reduced and critical failures such as electrolyte leakage or physical damage due to gas generated by electrochemical reaction or explosion may occur.
2. Voltage drop
Pay particular attention to the instantaneous working current and voltage drop due to the supercapacitor’s interal resistance when used in backup mode. The discharging current level is different depending on the supercapacitor’s inernal resistance.
