摘要： An end assembly seals a cylindrical electrochemical cell. The assembly includes a positive temperature coefficient (PTC) device and a gasket having a protrusion that cooperates with the end assembly isolates the PTC device from primary axial compression forces present in the closure assembly. In further embodiments of the present invention, the end assembly may be produced by insert molding a seal element about the terminal cover and the gasket itself has an E or F shaped cross section.

摘要： A closure assembly for an electrochemical cell including a container and an end assembly sealing an open end of the container in order to minimize mass or weight loss of the cell due to electrolyte vapor transmission is disclosed. The end assembly is provided with a vent member capable of venting a fluid when the pressure within the cell exceeds a predetermined limit; a contact member operatively in electrical contact with a conductive contact of the end assembly and a current collector of an electrode of the cell; and an insulating, polymeric seal member disposed at least between conductive components of the closure assembly having different polarities. In a preferred embodiment, the seal member has a selected dimensional ratio in order to minimize vapor transmission of the electrolyte through the seal member.
