An ultracapacitor is a capacitor with cells of a double electric layer, capable of high volumetric capacitance density derived from the use of high surface area electrodes and from storing energy in the diffuse double layer.

 

A double layer capacitor is often called a supercapacitor or an ultracapacitor for its remarkable qualities. Supercapacitors exhibit energy density much higher than conventional capacitors, and by power density they surpass all known types of batteries. Supercapacitors found their first application in military projects, for instance, starting engines of battle tanks and diesels of submarines or replacing batteries on boards of missiles. Econd organization produces 10 standard types of supercapacitors of various sizes. Most common applications are: starting diesel trucks, railroad diesel locomotives, actuators and in electric / hybrid electric vehicles for transient load leveling as well as for regenerating of the energy of braking. For instance NASA used 30 large Econd supercapacitors in its turbo-electric city bus. (Look for NASA site.)
