A mechanically rechargeable air-metal source of current having one or mor e non-consumable gas diffusion positive electrode(s), one or more consumable negative metal electrode(s), an electrolyte based on water solutions of salts and/or bases and a housing enclosing the positive electrodes) and the negative electrode(s), to create an inter-electrode gap, together with the electrolyte. The negative electrode(s) comprise(s) a metal selected from the group consisting of aluminum, zinc, magnesium, and alloys thereof, and further comprises) an effective amount of one or mor e additives selected from the group consisting of Ga, In, TI, Sn, Cd, Pb, Mn, and Fe. The effective amount of the additives improves the electrochemical characteristi cs of the negative electrode, reducing corrosion, and preserves the negative electrode(s) while being stored. The electrolyte is a salt solution, an alkali solution or a mixture of a salt solution and an alkali solution. The electrolyte may further have an additio n of Sn+4, Pb+4, Ga+3, In+3, poly-saccharide based on D-glucose, polyesters incl. amide s, 2-3 C alcohols and halogenides/hydroxides of alkaline metals, to provide a decreas e in anode corrosion during discharge, an increase in electric capacity of said electrolyte, a decrease of freezing temperature of saidelectrolyte, a change of chemical reaction results into microcrystalline form and stabilization of said electrolyte during storage.
