What is a supercapacitor?

A supercapacitor is a specially designed capacitor which has a very large capacitance. Supercapacitors combine the properties of capacitors and batteries into one device. Supercapacitors have charge and discharge times comparable to those of ordinary capacitors.

What is the difference between a capacitor and a supercapacitor?

A capacitor is a pair of two conductors of any shape, which are separated through a small distance or in close proximity and have equal and opposite charge. In other words, a capacitor is a device that stores electric energy. A supercapacitor is also a capacitor but its capacitance value is much higher than other capacitors.
