Patent attributes
A multilayered high performance capacitor formed of two or more conductors with a dielectric layer and one or more a dielectric-conductor interface layer sandwiched in between the conductors. The capacitor may be fabricated using many thin layers, at the nano level, providing a nanocapacitor. The capacitor may employ an interleaved structured where numerous conductor layers are interleaved with other conductor layers. The dielectric layers may be multilayered or a single layer and may consist of materials with high dielectric constants ranging from 800 to over 1 million, including materials in the perovskite-oxide family. The capacitor can be shaped, sized and the appropriate materials selected to obtain breakdown voltages within the range of 0.1 to over 11 MV/cm and to obtain specific energies and energy densities equivalent to or exceeding the power characteristics of known capacitors, fuel cells, and batteries. The nanocapacitor may be combined with other nanocapacitors to form stacks, packs, or grids of cells where the cells may be connected in series, parallel or both to provide increased energy or power characteristics.
