Super capacitors

Supercapacitors 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 supercapacitor. This concept is similar to an electrical charge that builds up when walking on a carpet. The supercapacitor 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 supercapacitor crosses into battery technology by using special electrodes and some electrolyte. Supercapacitors 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.
