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.

Abstract: A sealed galvanic cell comprising a container and a cover having a coiled electrode assembly disposed in the container. The coiled electrode assembly has an inner exposed electrode of one polarity and an outer exposed electrode of the opposite polarity. A flexible electrically conductive member secured to the cover makes electrical contact with the inner exposed electrode and exerts a radially outward force therein while the outer exposed electrode makes electrical contact with the wall of the container.

Abstract: A two-piece cover for galvanic cells wherein the inner cover has at least one aperture therein through which electrolyte may be quickly dispensed and absorbed into a container having cell components therein in a manner which effectively prevents the sealing surfaces of the cell from being wetted by electrolyte.
