Abstract
A dual air electrode metal-air cell having a casing with an upper cathode mask wall, a lower cathode mask wall, and a side wall; an anode assembly having a layer of anode material positioned above and below an anode collector and means, that may be a membrane or a solid foil current collector, for inhibiting movement of anode material between the two layers; separator materials covering the anode assembly on at least its upper and lower sides; an upper air cathode positioned between the upper cathode mask wall and the separator materials on the upper side of the anode assembly; a lower air cathode positioned between the lower cathode mask wall and the separator materials on the lower side of the anode assembly; a gas vent positioned on one or more of the side walls of the casing; and a liquid electrolyte substantially trapped by the separator materials. The separator materials comprise one or more layers of an absorbent fibrous web and one or more layers of a microporous membrane that, when wet, is gas-impermeable and liquid-permeable.
