The supercapacitor, also known as Electrochemical Double Layer Capacitors (EDLCs), differs from a regular capacitor in that it has a very high capacitance. A capacitor stores energy by means of a static charge as opposed to an electrochemical reaction. Applying a voltage differential on the positive and negative plates charges the capacitor.
Super Capacitor Datasheet: TS12S-R
This technology as applied to mobile/cellphones won a young scientist $50,000 in the recently concluded Intel International Science and Engineering Fair. It will just charge your mobile/cellphone in seconds rather than hours. Super capacitors will be the future of enegry storage.
