Abstract
The invention is embodied in a structure for containing an alkali metal battery. A closed metal housing includes a flange having an opening therethrough. An electronically and ionically insulating ceramic member is bonded to an exterior surface of the metal housing and encircles the opening through the flange thereby to define a passageway which is an extension of the opening. An electrically insulating, cation-permeable barrier to mass liquid transfer has an interior volume and an exterior surface area. The cation-permeable barrier is bonded to the ceramic member in such a manner that the interior volume of the metal housing, the passageway defined by the ceramic member and the interior volume of the cation-permeable barrier form a first closed electrode reaction zone. A container, including a structure bonded to the ceramic member, defines a closed container which encloses the exterior surface area of the cation-permeable barrier, the volume between the interior surface area of the container and the exterior surface area of the cation-permeable barrier forming a second closed reaction zone.
