An electrochemical cell container having pressure-relief means. An end wall of the cell has a central portion aligned with the central axis of the cell and has pressure-relief tabs remote from the central axis. The pressure-relief tabs are partially bounded by score lines, and bridge portions are provided for retaining the central portion when the score lines rupture to relieve excess pressure within the cell. The retained central portion holds solid internal components within the cell. Upon rupture of the score lines the, tabs serve as vanes for directing the discharged fluids so as to minimize translational acceleration of the cell caused by the discharged fluids.
