More Power for Tomorrow's Supercapacitors

As supercapacitors emerge to become an important feature in the world of battery devices, researchers at CIRIMAT1 in Toulouse and at Drexel University in Philadelphia have made a breakthrough discovery that invalidates years of preconceptions.

Supercapacitors, also known as ultracapacitors, are rechargeable high-power energy storage devices. They are currently used in personal electronics from mobile phones to cameras, as well as in hybrid electric and fuel-cell vehicles. They have the ability to store at least one million times more energy per unit mass than standard capacitors. They also have an indefinite lifespan as they can be charged and discharged an unlimited number of times. Until now, their usefulness was limited by their maximum capacitance–the measure of the amount of electric charge that can be stored.
