ABSTRACT:
A galvanic cell is disclosed comprising a porous cathode and an anode including a metal less noble than zinc selected from the group consisting of lithium, sodium, magnesium, calcium and aluminum. The cell also includes an electrolyte for electrolytic conduction between the cathode and anode which electrolyte comprises a solvent including thionyl chloride. A first solute consisting essentially of a salt of the selected anode metal is dissolved in the solvent in a concentration of between 0.5 and 3.0 moles per liter. A second solute selected from the group of compounds consisting of phosphoryl chloride, sulfolane, sulfur dioxide and mixtures thereof is also dissolved in the solvent in a concentration of between 0.5 and 6.0 moles per liter.
