What are the advantages of supercapacitors compared to ordinary capacitors?

Supercapacitor is a new type of electrochemical component that stores energy through polarized electrolytes. No chemical reaction occurs during the energy storage process, and this energy storage process is reversible, so supercapacitors can be charged and discharged repeatedly hundreds of thousands of times, so supercapacitors are also called double-layer capacitors, golden capacitors, farad capacitors, etc.

Ordinary capacitors are a kind of static charge storage medium, which can retain the charge for a long time. They are widely used and are indispensable electronic components in the field of electronic power.

Supercapacitors and ordinary capacitors are both capacitors, so why are supercapacitors more popular than ordinary supercapacitors?

1. Compared with ordinary capacitors, supercapacitors have a larger capacitance, reaching the farad level, while ordinary capacitors have a capacitance as small as microfarad level.

2. Supercapacitors can be charged and discharged hundreds of thousands of times and have a long service life. Ordinary capacitors can only be charged and discharged hundreds of times and have a short service life.

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

4. Supercapacitors have good ultra-low temperature characteristics and can work at -40℃ ~ +70℃. The working performance of ordinary capacitors is greatly reduced at low temperatures.

5. It has strong charge retention capability and low leakage. Ordinary capacitors need to be charged frequently to maintain their status.

6. The production and manufacturing process of supercapacitor materials does not cause environmental pollution and is an ideal green and environmentally friendly power source, while ordinary capacitors cause pollution and impact on the environment.

Due to these advantages, supercapacitors are often used in power supplies for electronic equipment, new energy vehicles, circuits, and other industries. Emergency lighting systems and high-power electric pulse equipment. Ordinary capacitors are mainly used in power filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, and various tributary circuits.

Supercapacitors have the above advantages and are very popular. Therefore, many unscrupulous merchants mix good quality and inferior supercapacitors and sell them wholesale. Therefore, you must be careful when purchasing supercapacitors.
