The invention provides a multi-cell, sealed, zinc-oxygen battery, comprising a container containing (a) a plurality of bi-cells, each cell having a housing provided with two major surfaces and accommodating a pair of oppositely-disposed, spaced-apart, air-permeable, liquid-impermeable cathodes in th
The invention provides a multi-cell, sealed, zinc-oxygen battery, comprising a container containing (a) a plurality of bi-cells, each cell having a housing provided with two major surfaces and accommodating a pair of oppositely-disposed, spaced-apart, air-permeable, liquid-impermeable cathodes in the form of oxygen-reduction electrodes, and defining between themselves a cavity configured to accommodate an anode of the battery and electrolyte, substantial portions of the major surfaces of the housing being removed, thus exposing major portions of the oxygen electrodes, and wherein the two major surfaces are partly recessed in such a way as to form, in conjunction with a similarly-recessed outer surface of a major wall of an adjacent cell housing, an inter-cathode gas space between adjacent cells with a plurality of oxygen access openings leading thereto; (b) a dead space volume between inner surfaces of the housing and the plurality of bi-cells; and (c) pressurized oxygen supply means for feeding oxygen to the dead space volume, for consumption in the inter-cathode gas spaces.
