What are Supercapacitors?
Supercapacitors (double-layer or ultracapacitors) are devices that store extremely large amounts of charge (from 0.022 F to 55 F) much more than a normal capacitor. Their level of energy storage approaches around 1/10 that of a low-density battery. But, unlike a battery, the power output can be 10 times greater (a handy feature in high-current…

Capacitors, Capacitance and Charge
Introduction to Capacitors A capacitor is an electrical device that is used to store electrical energy. A capacitor consists of two metal plates separated by an insulator called a dielectric. It stores electricity in the form of an excess of electrons on one plate and a deficiency on the other. In this state, the capacitor…
