Super Capacitors

Super Capacitors are capacitors which have the ability to store large amounts of charge, and therefore energy, in a very small volume. Energy storage is by means of static charge rather than of an electro-chemical process that is inherent to the battery. Applying a voltage differential on the positive and negative plates charges the super Capacitor. This concept is similar to an electrical charge that builds up when walking on a carpet. The super Capacitor was first conceived in 1957 but now research is focused on using these as a light weight power sources as an alternative for batteries. The super Capacitor crosses into battery technology by using special electrodes and some electrolyte.

Super Capacitors could find applications such as temporary back-up power supplies in the electrical power grid or providing the initial burst of energy to get electric cars moving.
