Super capacitor, also known as electrochemical capacitors, electric double layer capacitors, gold capacitors, and farad capacitors, are electrochemical components that have been developed by polarized electrolytes since the 1970s and 1980s. It is different from the traditional chemical power source. It is a kind of power source with special performance between the traditional capacitor and the battery. It mainly relies on the electric double layer and the redox tantalum capacitor to store electric energy. However, there is no chemical reaction in the process of energy storage. This energy storage process is reversible, and it is precisely because this super capacitor can be repeatedly charged and discharged hundreds of thousands of times.
