1. A battery system, comprising:
a generally prismatic enclosure having opposed first and second major walls with respective first and second perimeters and respective first and second widths, a perimetral wall connecting the first and second major walls along the first and second perimeters and including one or more generally flat perimetral surfaces, and an interior defined by the first and second major walls and the perimetral wall, wherein the enclosure is configured for containing an anode assembly, a cathode assembly and an electrolyte operatively disposed within the interior, and wherein the perimetral wall has a perimetral wall width as measured between the first and second major walls;
a longitudinal embossment formed in the perimetral wall extending outward from the interior and from the one or more generally flat perimetral surfaces and extending along opposed adjacent portions of the first and second perimeters, wherein the longitudinal embossment has an embossment width that is less than the perimetral wall width and an outer width as measured across the opposed adjacent portions of the first and second perimeters that is greater than either of the first and second widths;
a wall port defined in the perimetral wall in fluid communication with the interior, wherein the wall port is configured for permitting flow of the electrolyte therethrough into and out of the interior; and
first and second electrodes each extending through the perimetral wall and configured for electrical connection with the anode assembly and cathode assembly, respectively.
