What is a super capacitor?

A supercapacitor is a new type of energy storage device, different between a conventional capacitor and a rechargeable battery. 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.

How does a Supercapacitor Work?

How does a Supercapacitor Work?

Ultracapacitor mainly relies on the electric double layer and the redox tantalum capacitor to store electric energy. But there is no chemical reaction during 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. Ultracapacitors release energy quickly at peak times, then store it quickly and capture excess energy.

Advantages of Ultra Capacitors

Ultracapacitors not only have the characteristics of fast charge and discharge of capacitor, but also has the characteristics of energy storage of battery.
