ABSTRACT:
A final closure sealing member and a method for hermetically sealing an opening, such as an electrolyte fill opening in an electrochemical cell or a battery, are disclosed. After a cell is fully assembled and filled with electrolyte, the present sealing member is force-fit into sealing registry with the electrolyte fill opening to form a secondary seal for the cell. Preferably, an outwardly facing portion of the sealing member is flush or slightly recessed with the side wall surrounding the fill opening. Then, the outwardly facing portion is welded to the opening side wall to form a primary hermetic seal.
