Abstract:
1. A method for storing energy, the method comprising: a. providing an array of nanocapacitor cells, each capacitor cell including (1) a cathodic electrode; and (2) an anode spaced apart from the cathodic electrode by an intervening dielectric characterized by a thickness normal to the cathodic electrode and by an electron mean free path, wherein a thickness of the intervening dielectric is in the range between 0.1 nanometers and 1000 nanometers and is smaller than the electron mean free path within the dielectric, and wherein the cathodic electrode is at least 100 times larger than the thickness of the intervening dielectric in every direction transverse to the thickness dimension of the intervening dielectric; and b. storing an excess of electrons on the cathodic electrode.
