  • Electrochemical cell with improved gasket and seal
    Patent number: 6468691
    Abstract: Disclosed is an electrochemical cell using a gasket with projections on both surfaces of an upstanding wall. When used as a seal member between two parts of the housing of an electrochemical cell, a plurality of high compressive stress areas is formed in the gasket wall. When projections on opposite sides of the gasket are not horizontally aligned, an effective seal can be achieved with a thinner-wall gasket, providing more internal cell volume for active materials. Also disclosed is a process for assembling the cell.

  • Beaded electrode cup for a miniature galvanic cell
    Patent number: 6183902
    Abstract: A miniature galvanic cell employing a cell housing comprising a beaded cup, wherein the bead is disposed at the vicinity of the open end of the cup, and a low profile can and gasket assembly are used so that effectively the majority of the cross-section thickness of the vertical portion of the cell is attributed to only the thickness of the wall of the cup so that maximum internal volume of the cell is reserved for the active components. A process for producing the novel housing is also disclosed.
