  • Lithium iron disulfide battery
    Patent number: 10998535
    Abstract: A lithium-iron disulfide battery with improved high temperature performance is disclosed. The separator characteristics are deliberately selected to be compatible with the electrolyte at the intended temperature. Additional or alternative modifications can be made in the form of a scaffold or laminated structure. A preferred polymer for such separators is polyimide.
    Type: Grant

  • Lithium-iron disulfide cell design
    Patent number: 8460826
    Abstract: A lithium-iron disulfide electrochemical cell design is disclosed, relying on judicious selection of the electrolyte, a thicker lithium anode and a cathode with specific characteristics selected to cooperate with the electrolyte. The resulting cell has a reduced interfacial surface area between the anode and the cathode but, surprisingly, maintains excellent high drain rate capacity.

  • Closure assembly for electrochemical cells
    Patent number: 8383255
    Abstract: An end assembly seals a cylindrical electrochemical cell. The assembly includes a positive temperature coefficient (PTC) device and a gasket having a protrusion that cooperates with the end assembly isolates the PTC device from primary axial compression forces present in the closure assembly. In further embodiments of the present invention, the end assembly may be produced by insert molding a seal element about the terminal cover and the gasket itself has an E or F shaped cross section.

  • Lithium-Iron Disulfide Cell Design with Core Reinforcement
    Publication number: 20100273036
    Abstract: A electrochemical cell design, with particular applicability to lithium-iron disulfide batteries, is disclosed. The cell includes a spirally wound electrode assembly with a central core. The core causes uniform expansion within the cathode. The core may also collapse and/or possess a cross sectional shape that differs from the cross sectional shape of the cylindrical container which houses the electrode assembly.

  • Closure Assembly for Electrochemical Cells
    Publication number: 20100216014
    Abstract: A closure assembly for an electrochemical cell includes a positive temperature coefficient (PTC) device and a dual wall gasket that isolates the PTC device from primary axial compression forces present in the closure assembly. A method for closing an electrochemical cell to remove the PTC device from primary axial compression is also contemplated.
