  • alkaline electrolyte within said evelope;

    a rigid conductive plate within said envelope having a major face adjacent an inner face of one of said major walls of said envelope of a lateral extent generally conforming to and slightly less than said face of said one major wall;

    a connector conductively joined to said conductive plate and extending from the central region of said major face through said one major wall of said envelope at a central region thereof, said one major wall engaging said connector portion passing therethrough;

    an adhesive bond between said major face of said plate and said adjacent inner face of said one major wall of said envelope surrounding said extending connector and substantially coextensive with said major face of said plate;

    a continuously compressed resilient pad on the exterior of said one major wall of said envelope, said pad being substantially coextensive with said adhesive bond and surrounding said extended connector; and

    means to maintain said resilient pad compressed to apply generally uniform pressure through said resilient pad over the coextensive areas of said one major wall of said envelope, said adhesive bond and said conductive plate.
