The supercapacitor resembles a regular capacitorwith the exception that it offers very high capacitance in a small package.Energy storage is by means of static charge rather than of an electro-chemicalprocess that is inherent to the battery. Applying a voltage differential on thepositive and negative plates charges the supercapacitor. This concept issimilar to an electrical charge that builds up when walking on a carpet. Thesupercapacitor concept has been around for a number of years. Newer designsallow higher capacities in a smaller size.
Whereas a regular capacitor consists ofconductive foils and a dry separator, the supercapacitor crosses into batterytechnology by using special electrodes and some electrolyte. There are threetypes of electrode materials suitable for the supercapacitor. They are: highsurface area activated carbons, metal oxide and conducting polymers. The highsurface electrode material, also called Double Layer Capacitor (DLC), is leastcostly to manufacture and is the most common. It stores the energy in thedouble layer formed near the carbon electrode surface.
