ABSTRACT:
A metal-air battery is described having recirculating electrolyte. The battery comprises: (a) a tank defining a reservoir for liquid electrolyte, (b) a support panel mounted in the tank above the electrolyte reservoir, (c) a plurality of individually removable metal-air cells mounted in side-by-side relationship on said support panel with air gaps therebetween, each cell comprising a pair of spaced-apart flat side walls joined by end faces and top and bottom faces, said side walls including air cathodes, a metal anode mounted between and spaced from said flat side walls, an electrolyte inlet connector below the lower edge of the anode and an electrolyte outlet connector, said connectors being adapted to removably extend through openings in said support panel, and said outlet connector being adapted to return electrolyte to the reservoir, and (d) circuit means for connecting said cells to an external load.
