MOLECULAR HYPER CAPACITOR

Disclosed herein is an energy storage device, characterized as a molecular capacitor, and called hyper capacitor due its high energy density. It contains at least one modified electrode, formed by a composite material that mix at the mesoscopic nanoscale an electric conductive material with a molecular thin film, auto assembled or chemically or physically coupled, composed of active redox molecules in which the shielding of the electric field is of a mechanical quantum nature. The device has volumetric energy density above 35 Wh L.sup.−1 and gravity energy density above 140 Wh kg.sup.−1.
