ABSTRACT:
A metal/air battery having plural series-connected cells, including a tank for holding a body of liquid electrolyte, and an electrically nonconductive frame carrying a plurality of air cathodes facing a common air chamber and a like plurality of anodes respectively juxtaposed to the cathodes outside the air chamber, the frame 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 anodes may have vertical slots to facilitate passage of electrochemical reaction products from the anode-cathode gaps. The battery may be incorporated in a lamp having a light bulb in a cartridge slidably held between resilient arms with electrical contacts arranged as a switch to close an otherwise-open circuit including the battery and the light bulb when the cartridge is moved to the extremity of the arms.
