Abstract
A multi-cell metal/air battery is described having series-connected cells, including a tank for holding a body of liquid electrolyte, and an electrically non-conductive frame carrying a plurality of air cathode assemblies, each cathode assembly having a common air pocket and a pair of cathodes, and a like plurality of anodes respectively juxtaposed to the cathodes outside the air chamber, the air cathode assemblies being removably insertable in the tank and engaging the tank wall, when inserted, so as to divide the tank into a plurality of separate and substantially electrically isolated electrolyte-holding zones each containing one anode-cathode pair. The air cathode assembly may include an air circulation system to keep the air in the pocket fresh. The tank may also include an electrolyte distribution system and a flushing system for flushing the battery without the need to remove the cathodes and anodes from the tank.
