ABSTRACT:
Flanged U-shaped cup members abut the exterior of the negative electrode and positive electrode of a Li alloy/FeS.sub.x multi-cell battery array and function to form a peripherally sealed structural enclosure for these elements, while capturing and maintaining ceramic seal rings between respective flanges. The flanged cup-like members act in conjunction with either back-to-back similarly shaped and sized inverted flanged cup-like members or C-shaped upper and lower spacer rings whose vertical height is double that of the electrodes. At least one of the flanges of the electrode containment structure extends radially outwardly and downwardly oblique from the other flange of the C-shaped support structure, and the periphery thereof is welded to the periphery of a similar diameter juxtaposed cell cover ring to form a complete multi-cell envelope for the battery by welding of two seal assemblies together.
