Abstract
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.
