  • Lithium-halogen batteries
    Patent number: 4292346
    Abstract: Lithium-halide coatings for interior electrode lead portions in lithium halide batteries.
    Type: Grant
    Filed: August 22, 1979
    Date of Patent: September 29, 1981
    Assignee: Medtronic, Inc.
    Inventor: Lee F. Athearn
  • Expandable casing for electro-chemical cells
    Patent number: 4278744
    Abstract: An expandable air-impermeable casing for an electrochemical cell comprised of complemental flexible casing sections of a material which provides a diffusion barrier to atmospheric contaminants. The casing provides an expandable compartment for containment of active cell materials, the cell terminal members sealably projecting through the mated casing sections.A battery shell or container is formed by sealing two side sheets along predetermined linear regions to form several pockets or chambers for accommodating, respectively, the ingredients and elements of an organic cell, and when the respective cell pockets are closed and sealed, the cells thus formed are then folded along intermediate fold lines into a--Z--or accordion pleated form, and then disposed in a protective sealed box as a battery.
