The current increase in the usage of electricity as a primary source of energy has created exceeding application of batteries and energy storage devices, particularly capacitors. A revolutionary device in this trend is the electrical double-layer capacitor (EDLC) or ultracapacitor/ supercapacitor found in a diverse array of electronic equipment from daily usage laptops, hybrid and electric vehicles to windmills. High double-layer capacity of EDLC products and Low internal resistance (ESR).
