<p>An improved metal anode-oxygen diffusion cathode battery having an anode; an oxygen diffusion cathode; an aqueous electrolyte containing metal cations selected from the group consisting of alkali metal cations and alkaline earth cations; the improvement wherein said electrolyte comprises an additive selected from the group consisting of (a) metal cations of Pb, Sn, Ga and In at a cumulative concentration of 0.001 to 1 M; provided that when Pb, Ga and In is absent the concentration of Sn is greater than 0.2M; and provided that in the presence of both of Mg and Sn together, the concentration of In is greater than 0.2M; (b) an organic additive selected from the group consisting of 1-15 % W/W of a D-glucose polysaccharide, 0.5 - 5 % W/W of a polyester, 0.5 % of an aliphatic alcohol selected from ethyl alcohol and propyl alcohol, and mixtures thereof; and (c) a halide anion selected from the group consisting of F?-, Cl-, Br-, I-¿ and mixtures thereof.</p> |
