ABSTRACT:
A sealing gasket for an electrochemical cell disposed between the cell container and cover comprising an annular sidewall and an inwardly extending base flange, said sidewall having a nonuniform thickness such that the average thickness of that quarter of said sidewall immediately above said flange is greater than the average thickness of the sidewall at its top quarter, thereby enabling increased sealing surface area and increased terminal clearance.
