  • Electrochemical cell constructions and methods of making the same
    Patent number: 6737189
    Abstract: A method of making electrochemical cells with high anode-to-cathode interfacial surface area and improved discharge efficiency at high rate discharge, without sacrificing total capacity involves the use of a separator coated electrode, and a flowable material comprising a second electrode. The first electrode and flowable material comprising the second electrode are disposed in a cell housing. The flowable material surrounds the coated surfaces of the first electrode. The invention also provides simplified methods for making electrochemical cells having a high anode-to-cathode interfacial surface area.

  • Electrochemical cell having a safety vent closure
    Patent number: 5015542
    Abstract: A non-resealable vent closure for a galvanic cell, such as a nonaqueous cell, which comprises a seal member force-fitted with a bushing having an upper portion terminating with a thinner walled lower portion and wherein said seal member is force-fitted within the lower portion of the bushing and the bushing is seated within and seals the vent orifice in the housing of the cell.
    Type: Grant

  • Liquid cathode electrochemical cells having insured anode to tab contact
    Patent number: 4988585
    Abstract: Liquid cathode electrochemical cells have means for biasing a consumable metal anode against a separator and resultingly against a cathode collector. The biasing means contacts the active anode metal throughout the discharge of the cell.

  • Vent liner and cover construction for galvanic cells
    Patent number: 4931368
    Abstract: An electrochemical cell having a cell housing that contains the active components of the cell; the cell housing having a vent liner containment section that comprises a sealing well having a bottom disposed toward the interior of the cell, an orifice in the sealing well and a support ledge at the bottom of the sealing well; a vent liner having a vent liner orifice disposed within the sealing well so that an end of the vent liner abuts the support ledge, the orifice in the sealing well and the vent liner orifice providing a path from the interior of the cell to the atmosphere; and a seal member force-fitted within the vent liner, wherein the vent liner and the seal member are adapted so that the seal member will be at least partially expelled from the vent orifice at a predetermined internal gas pressure within the cell.
