Abstract: Devices for storing energy at a high density are described. The devices include a solid dielectric that is preformed to present a high exposed area onto which an electrode is formed. The dielectric material has a high dielectric constant (high relative permittivity) and a high breakdown voltage, allowing a high voltage difference between paired electrodes to effect a high stored energy density.
Abstract: Devices for storing energy at a high density are described. The devices include carbon-containing extensions which increase the surface area between a dielectric material and one or both of the electrodes. The dielectric material may have a high dielectric constant (high permittivity) and a high breakdown voltage, allowing a high voltage difference between paired electrodes to effect a high stored energy density.
