ABSTRACT:
This disclosure relates to a hermetically sealed alkali metal battery container. The battery includes a ceramic ring having upper and lower contoured surfaces thereon located on its outer circumferential surface. Outer metal casings defining an upper battery container and a lower battery container are formed so as to have a bell-shaped open end on each one. The bell-shaped open end of respective casings are located adjacent the contoured surfaces formed on the ceramic ring. Each bell-shaped open end of a metal casing has associated therewith a sealing band which engages the open end of the casing to compress the same into engagement with an associated contoured surface of the ceramic ring to form a hermetic seal therebetween.
