A bipolar battery assembly of the consumable metal anode type is described. Contact between internal battery elements is now enhanced by air assisted, internally exerted compressive force. Battery elements are constructed in modular manner that assists in the ease of battery assembly and disassembly. Furthermore, ease of anode replenishment is maintained. A multitude of individual cells can now be joined together in an efficient bipolar assembly cell stack for augmented electrical energy generation. In addition to being bipolar, the battery is of rugged construction, providing for dependable, long-life operation that is desirably maintenance-free.

a metal-air bipolar battery, said battery having at least one cell, said battery comprising: a consumable, plate-like metal anode, said anode having pressed against a broad face thereof a solid conductive anode current collector, which current collector has, on the side opposite the side pressed against the anode, conductive and compressible metal spring members affixed to said anode current collector and extending away therefrom across an air chamber; an electrically conductive porous metal member with said compressible metal spring members extending across said air chamber and come into pressing contact against a broad planar face of said porous metal member, or into contact with an electrically conductive apertured facing element for said porous metal member, which porous metal member extends in a direction opposite from the metal spring members into face-to-face electrically conductive contact with, an air cathode which, on its broad planar surface opposite from the porous metal member, is exposed to a chamber that is situated between said air cathode and metal anode, said chamber serving to permit the passage of battery electrolyte between anode and cathode.
