  • Patent number: 8252452
    Abstract: Disclosed herein are a secondary battery including an electrode assembly for charging and discharging mounted in a sheathing member including a metal layer and a resin layer, wherein the secondary battery further includes a secondary battery having a molding part of a predetermined thickness at least partially formed at the outside of a sheathing member, preferably, at a sealing region of the sheathing member, and a medium- or large-sized battery pack including the same. The molding part is formed at the outside of the sheathing member of the secondary battery. Consequently, the secondary battery according to the present invention has high mechanical strength, and therefore, it is possible to construct a battery pack without using addition members, such as cartridges. When the molding part is formed at the sealing region, which is weak, the molding part increases the mechanical strength and the sealing force of the secondary battery.

  • Patent number: 8092934
    Abstract: In one embodiment, an energy storage device comprises a container containing a first electrode generating a positive charge, a second electrode generating a negative charge, and an electrolyte in ionic contact with the electrodes. The container comprises a base and one or more walls defining an opening in the container, the base having a first terminal in electrical connection with the first electrode. A cap is shaped to close the opening and is electrically isolated from the container, while having a second terminal in electrical connection with the second electrode. A collector plate is interposed between the first electrode and the base and is electrically conductive, providing the electrical connection between the first electrode and the first electrical terminal and exhibiting an extension with a concave side oriented in the direction of the base, which is connected to the base by interference fitting against a mating protrusion on the base.

  • Patent number: 8088506
    Abstract: The invention is an electrochemical battery cell with a fluid consuming electrode, such as an oxygen reduction electrode, and a fluid regulating system. The fluid regulating system includes a valve for adjusting the rate of passage of the fluid to the fluid consuming electrode. It is operated by an actuator that responds (e.g., by deforming) to changes in a potential applied across the actuator to open or close the valve. The applied potential can be the cell potential or an adjusted potential. The potential applied across the actuator can vary according to the need for more or less fluid in the fluid consuming electrode. The valve can be contained within the cell housing, for example between the fluid consuming electrode and one or more fluid entry ports in the cell housing, or it can be located outside the cell housing.
