  • Publication number: 20230253631
    Abstract: An electrochemical storage cell may comprise first and second electrode sheets wound around a cylindrical core forming a jellyroll structure, the first and second electrode sheets each comprising uncoated conductive edges parallel to end faces of the jellyroll structure, and coated opposing surfaces between the uncoated conductive edges, first and second separator sheets mechanically and electrically separating the coated opposing surfaces of the first and second electrode sheets and mechanically and electrically separating the cylindrical core and the coated opposing surfaces of the first electrode sheet, and slotted cutouts from the uncoated conductive edges, the slotted cutouts angularly co-located relative to the cylindrical core upon forming the jellyroll structure.

  • Publication number: 20100192727
    Abstract: An apparatus 2 and method for mixing, agitating and transporting a slurry of molten or semi-solid metal or metal-matrix composite material including a casing 1 for containment of the slurry. An electrical conductor means 10 applies to the slurry a moving magnetic field to induce flow thereof. A component 7,8 is secured and located within the casing to modify the flow pattern of the slurry induced by the moving magnetic field.

  • Publication number: 20040261970
    Abstract: Method and apparatus for producing semi-finished or finished products from metal-based material. The apparatus includes a mixing furnace to receive a metal-based material to be formed; temperature control means to maintain the metal-based material in a thixotropic semi-solid state in the mixing furnace; rotatable mixing means operable in the mixing furnace to subject the metal-based material to a mixing and shearing action while imparting a centrifugal force; and supply means to move the material to a delivery site. Optionally, injection means are provided to inject the material from an introduction chamber of a casting machine into a mold or die cavity while the material is in a thixotropic semi-solid state.
