1) Supercapacitor is an electrochemical energy storage device in the “power” industries.Compared with battery, supercapacitor has one-tenth of energy, but delivers over 10 times power due to ultra low ESR. It operates more reliably in wider temperature and its life is semi-permanent, over 500,000 cycles.


2) An super capacitor (also called ultra capacitor, ultracapacitor, electric double-layer capacitor) differs from an ordinary capacitor in two important ways: its plates effectively have a much bigger area and the distance between them is much smaller, because the separator between them works in a different way to a conventional dielectric.The plates are made from metal coated with a porous substance such as powdery, activated charcoal, which effectively gives them a bigger area for storing much more charge.
