A method of initially assembling and then subsequently hermetically sealing a container portion of an alkali metal battery to a ceramic portion of such a battery is disclosed. Sealing surfaces are formed respectively on a container portion and a ceramic portion of an alkali metal battery. These sealing surfaces are brought into juxtaposition and a material is interposed therebetween. This interposed material is one which will diffuse into sealing relationship with both the container portion and the ceramic portion of the alkali metal battery at operational temperatures of such a battery. A pressure is applied between these sealing surfaces to cause the interposed material to be brought into intimate physical contact with such juxtaposed surfaces. A temporary sealing material which will provide a seal against a flow of alkali metal battery reactants therethrough at room temperatures and is applied over the juxtaposed sealing surfaces and material interposed therebetween. The entire assembly is heated to an operational temperature so that the interposed material diffuses into the container portion and the ceramic portion to form a hermetic seal therebetween.

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.
