Supercapacitor, also known as electrochemical capacitor, double layer capacitor, gold capacitor, Farad capacitor, is an electrochemical component developed from the 1970s and 1980s to store energy through polarized electrolyte. Above is the supercapacitor definition. It is different from the traditional chemical power supply. It is a kind of power supply with special performance between the traditional capacitor and battery, mainly relying on double layer and redox pseudocapacitor charge storage of electrical energy. However, there is no chemical reaction during the energy storage process, which is reversible and types of supercapacitors can be recharged and discharged hundreds of thousands of times.
