ABSTRACT:
A reserve battery which includes a plurality of series-connected battery cells which are simultaneously filled with electrolyte from a reservoir through a like plurality of filling conduits formed of electrically-insulating material and connected respectively between the reservoir and the cells. In one embodiment, the cross-sectional area of each filling conduit is several orders of magnitude smaller than the area of each cell electrode active surface and the length of each filling conduit exceeds the square root of the filling conduit cross-sectional area by at least two orders of magnitude, to thus minimize intercell short circuits. In another embodiment, each filling conduit includes a gas generator disposed therein to contact electrolyte flowing therethrough and formed of a material which generates a gas when brought into contact with the electrolyte, so that after the cell has been sufficiently filled with electrolyte, gas generated by the gas generator will displace electrolyte in the filling conduit to thus electrically isolate the cell from the reservoir.
