A new primary battery has been developed comprising a zinc anode, a potassium iodate cathodic reactant, and an electrolyte consisting substantially of sulfuric acid. A reserve battery of this type is capable of comparatively high current drain rates, typically 0.092 amp/cm 2 (0.6 amp/in. 2 ) at a discharge potential of 1.6 v for 7 min. A typically self‐contained battery capable of operating at the above performance level has an energy output of 2.32 watt min/cm 3 and watt min/g output of 1.88. Procedures have been developed for manufacturing low cost cells in a simplified type of mechanical battery construction. Prototype batteries have been constructed and experimental data are given on their performance.
