  • CAPACITORS USING PREFORMED DIELECTRIC
    Publication number: 20100226066
    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.
    Type: Application
    Filed: February 2, 2010
    Publication date: September 9, 2010
    Applicant: Space Charge, LLC
    Inventors: Daniel C. Sweeney, John B. Read
  • CAPACITORS USING CARBON-BASED EXTENSIONS
    Publication number: 20100195263
    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.
