Dielectric material between capacitor electrodes increases the capacitance. However, when the electric field exceeds a threshold, electric breakdown in the dielectric discharges the capacitor suddenly and the stored energy is lost. We show that nanovacuum tubes do not have this problem because (i) electric breakdown can be suppressed with quantization phenomena, and (ii) the capacitance is large at small gap sizes. We find that the energy density and power density in nanovacuum tubes are large…

Large energy storage efficiency of the dielectric layer of graphene nanocapacitors

The energy storage capabilities of graphene nanocapacitors are examined, which are tri-layer devices involving an Al film, Al2O3 dielectric layer, and a single layer of carbon atoms, i.e., graphene, and it is discovered that the amount of charge stored in the dielectrics can be equal or can even exceed the amountof charge stored on the capacitor plates.

Nuclear energy conversion with stacks of graphene nanocapacitors

It is shown that during the deceleration process more than 90% of kinetic energy of charged nuclear reaction products is converted to electric energy and stored as electric energy in a stack of charged capacitors with a gap size of 500 nm and graphene electrodes.
