  • 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.

  • Alkaline electrochemical cell having a non-crimped closure
    Patent number: 7267905
    Abstract: An adhesive closure for sealing closed the open end of an electrochemical cell container. The electrochemical cell comprises a can having an open end and a side wall, and positive and negative electrodes disposed in the can. The cell also has a cover disposed on the open end of the can and having a peripheral wall radially outside of the side wall of the can. One or more adhesives are disposed between the outer side wall of the can and the peripheral wall of the cover for adhering the cover to the can.

  • Electrochemical cell having venting current collector and seal assembly
    Patent number: 7122270
    Abstract: A low profile collector and seal assembly for sealing the open end of a container of an electrochemical cell and providing venting of pressurized gases. An electrochemical cell has a can with a closed bottom end and an open top end, positive and negative electrodes disposed in the can, and a collector and seal assembly disposed in the open top end of the can for closing the open top end of the can. The collector and seal assembly includes a current collector and an annular seal that move relative to each other from a sealed position to a vented position when the internal cell pressure reaches a pressure threshold to vent pressurized gases.
