Supercapacitors are also known as ultracapacitors or double-layer capacitors. They bridge the gap between capacitors and batteries. Supercapacitors display higher energy density than a conventional capacitor and higher power density than batteries.

A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure (PageIndex{1}).
capacitor will charge up and its voltage will increase. During this time, a current will flow producing a voltage across the resistor according to Ohm''s Law, V = IR.
