  • HOLLOW CORE GRANULES, PRODUCTS INCORPORATING THE GRANULES, AND METHODS OF PREPARING THE GRANULES
    Publication number: 20210237035
    Abstract: The present disclosure relates to hollow core granules, products incorporating the hollow core granules, and methods of making the hollow core granules. The hollow core granules can comprise at least one wall surrounding a cavity that is devoid of any solid or liquid so as to define a hollow core, the at least one wall comprising a plurality of individual particles of at least one wall forming material, the plurality of individual particles sufficiently bound together so that the at least one wall is structurally self-sustaining. The hollow core granules further can include a binder material present in the at least one wall. The hollow core granules can be useful as a standalone material and/or may be useful in preparing a variety of products wherein the hollow core granules may be mixed or otherwise combined with further components. The disclosure further provides methods of making such hollow core granules.

  • Method for manufacturing an energy storage device
    Patent number: 7888229
    Abstract: The present invention relates to methods of manufacturing an electrochemical energy storage device, such as a hybrid capacitor. The method comprises saturating a porous electrically conductive material in a solution comprising an organic solvent and a metal complex or a mixture of metal complexes; assembling a capacitor comprising the positive electrode made of porous electrically conductive material saturated with a metal complex, a negative electrode, and a separator in a casing; introducing the electrolyte solution into the casing; sealing the casing; and subsequent charge-discharge cycling of the capacitor. The charge-discharge cycling deposits a layer of an energy-accumulating redox polymer on the positive electrode. The electrolyte solution for filling the hybrid capacitor contains an organic solvent, a metal complex, and substances soluble to a concentration of no less than 0.01 mol/L and containing ions that are electrochemically inactive within the range of potentials between ?3.0 V to +1.5 V.
