  • Patent number: 11211615
    Abstract: Various embodiments are directed to an electrochemical cell having a non-homogeneous anode. The electrochemical cell includes a container, a cathode forming a hollow cylinder within the container, an anode positioned within the hollow cylinder of the cathode, and a separator between the cathode and the anode. The anode comprises at least two concentric anode portions, defined by different anode characteristics. For example, the two anode portions may contain different surfactant types, which provides the two anode portions with different charge transfer resistance characteristics. By lowering the charge transfer resistance of a portion of an anode located proximate the current collector of the cell (and away from the separator) relative to an anode portion located adjacent the separator, improved cell discharge performance may be obtained.

  • Patent number: 8563150
    Abstract: The invention concerns a device for catalytic recombination of gases for alkaline batteries with shortened zinc anode. The invention concerns a device for catalytic recombination of gases formed when charging a zinc anode alkaline battery, characterized in that it consists of a catalytic mass in contact with a crosslinked cellular metal foam serving as catalyst support and heat dissipating structure, said catalytic mass consisting of a mixture of carbon black including metal of platinum metals, and of a hydrophobic binder, the whole assembly being heat-treated to cause the hydrophobic binder of said catalytic mass to be sintered. Said device is advantageously connected to one of the terminals of the battery or to any other metal part constituting part of the cover of the battery case, so as to promote discharge of the calories produced.

  • Patent number: 8383259
    Abstract: In the case of a safety device for an accumulator cell, which has an electrode assembly disposed in an elastic cell sheath and at least one electrical connector, a blocking element is provided which blocks at least a first electrical contact associated with the electrical connector with at least a second electrical contact in a releasable electrical connection, the blocking element being configured for the purpose of releasing the releasable electrical connection when the cell sheath expands as a result of a change in volume of the accumulator cell during operation. A separation of the second contact from the first contact is thereby made possible.

    Abstract: In an electrochemical energy store device, the electrochemically active components (11, 13, 21, 23, 31, 33), or additional components (12, 22, 32), are designed and/or arranged in a hermetically sealed container such that they inhibit the process of a chemical reaction of the electrochemically active components of the energy store device as soon as positive pressure builds, or could build, inside the container as a result of said chemical reaction. Preferably, the flow (14, 34, 35) of a movable component into the area of a chemical reaction, in which said movable component participates as a reactant, is inhibited or suppressed, at least locally, as soon as positive pressure build, or could build, inside the container as a result of said chemical reaction.

  • Patent number: 8236439
    Abstract: A rechargeable battery according to an exemplary embodiment of the present invention includes an electrode assembly, a case containing the electrode assembly, and a cap assembly. The electrode assembly includes a first electrode, a second electrode, and a separator between the first and second electrodes. The cap assembly is coupled to the case. The cap assembly includes a tab that is electrically connected to the first electrode and a deformable plate that is electrically connected to the second electrode. The deformable plate also includes a notch that is opened due to an increase of pressure. The deformable plate deforms as a result of increased pressure and electrically contacts the first tab, short circuiting the rechargeable battery.

  • Patent number: 7964300
    Abstract: There is provided a risk-free and easy-to-use battery pack using battery cells 1 as a secondary battery, in which internal gases evaporated by applying overvoltage or the like thereto are processed inside a case to be prevented from leaking to the outside of the case and thereby even if the case has been led to rise in pressure due to a thermorunaway of the battery, the case is free from breaking. To realize this performance, the battery pack 10 is provided with a battery cell housing 17 for housing lithium cells 1 and a gas processor 15 for liquefying the internal gases g generated from the lithium cells 1.
