The obvious advantage of supercapacitors is that they can be cycled more than a thousand times before aging, while batteries can only be cycled hundreds of times. In many electronic products, capacitors are indispensable electronic components. The functions of the Farad capacitor module in the circuit are smooth filtering, decoupling, AC signal bypass, AC and DC coupling, etc. A capacitor is an electronic component consisting of two conductors with an insulator (dielectric) sandwiched between them.

Supercapacitors have exceptionally large storage capacities, on the order of Farads. Due to its high power density, long cycle life, safety and reliability, etc., it has been widely used in hybrid electric vehicles, DC high-power output equipment and other industries.

In terms of composition, supercapacitors are mainly composed of auxiliary materials such as electrodes, electrolytes, diaphragms, and lead. Among them, electrodes, electrolytes and diaphragm materials play a decisive role in the safety performance of Farad capacitors. The charging rate of supercapacitors is high, and the electrode material structure will not be disturbed during charging. Superposition of long-term storage will not reduce the capacitor voltage, so the cycle life is long, which can reach more than 105 times;

In the power industry, supercapacitors are mainly used in wind and solar power generation. One is that the supercapacitor is used as a backup power source for the wind power generation system. In the event of a power supply stop, turning the direction of the blades to a safe and reliable place can ensure the safe and reliable operation of the electric wind power generation system.

The whole process of charging and discharging the supercapacitor module has always been a physical process without chemical reaction. Therefore, the safety performance is relatively stable, which is different from the battery through chemical reaction.
