<p>An electrical-energy-storage unit (EESU) has as a basis material a high-permittivity composition modified barium titanate ceramic powder. This powder is single coated with aluminum oxide and then immersed in a matrix of poly(ethylene terephthalate) (PET) plastic for use in screen-printing systems. The ink that is used to process the powders via screen-printing is based on a nitrocellulose resin that provide a binder burnout, sintering, and hot isostatic pressing temperatures that are allowed by the PET plastic. These lower temperatures that are in the range of 40°C to 150°C also allows aluminum powder to be used for the electrode material. The components of the EESU are manufactured with the use of conventional ceramic and composition-modified barium titanate powder, sintering to a closed-pore porous body, followed by hot-isostatic pressing to a void-free body. The 31,351 components are configured into a multilayer array with the use of a solder-bump technique as the enabling technology so as to provide a parallel configuration of components that has the capability to store at least 52.22 Kw·h of electrical energy. The total weight of an EESU with this amount of electrical energy storage is 281.56 pounds including the box, connectors, and associated hardware.</p> |
