What are the advantages of supercapacitors over ordinary capacitors?

Supercapacitor is a new type of electrochemical element, which stores energy by polarized electrolyte. There is no chemical reaction in the energy storage process, and this energy storage process is reversible. Therefore, the super capacitor can be repeatedly charged and discharged hundreds of thousands of times. Therefore, the super capacitor is also called electric double-layer capacitor, gold capacitor, farad capacitor, etc.

The ordinary capacitor is a kind of static charge storage medium, and the charge can be retained for a long time. Widely used, it is an indispensable electronic component in the field of electronic power.

Supercapacitors and ordinary capacitors are also used as capacitors. Why are supercapacitors more popular than ordinary supercapacitors?

1. The capacitance of super capacitor is larger than that of ordinary electric capacity, and has reached farad level. The capacitance of ordinary capacitance is as small as micro method.

2. The super capacitor can be repeatedly charged and discharged hundreds of thousands of times, and the service time is long. Ordinary capacitors can only be charged and discharged for hundreds of times, and the use time is short.

3. The charging speed is faster than that of ordinary capacitors. It can reach more than 95% of the rated capacity in 10 seconds to 10 minutes.

4. Super capacitor has good ultra-low temperature characteristics and can work at -40 ℃ ~ +70 ℃. The working performance of ordinary capacitor at low temperature is greatly reduced.

5. It has strong charge retention ability and small leakage. Ordinary capacitors need to be regularly charged to maintain the state.

6. The production and manufacturing process of super capacitor materials do not cause environmental pollution, so it is an ideal green power supply, while ordinary capacitors cause pollution and impact on the environment.

Because of these advantages, supercapacitors are often used in power supply such as electronic equipment, new energy vehicles, circuits and other industries. Emergency lighting system and high-power electric pulse equipment. Common capacitors are mainly used in power filter, signal filter, signal coupling, resonance, filter, compensation, charge and discharge, energy storage, various tributaries and other circuits.
