Abstract
In a method for fabricating lightweight bipolar metal-gas battery cell stacks (1), a segmented frame (21, 23) for insulating and mechanically supporting the stack (1) is fabricated of dielectric materials. Each cell (3) has associated therewith first and second frame segments (21, 23) associated with negative and positive electrodes (5, 7, respectively). Weld tabs (25, 27) are welded to the negative and positive electrodes (5, 7, respectively), and are welded together external to the cell frame (21, 23). Electrolyte is added to each cell (3), preferably as it is fabricated within the enveloping cell frame segments (21, 23). Alignment rods (34) align the stack (1) components, and assist in compression-sealing adjacent frame segments (21, 23) by means of compressing mating tongues (43) and grooves (41).
