Abstract
The addition of elemental sulfur to the cuprous chloride active material increases the electrode potential throughout discharge by approximately 0.4v when operated in neutral or acidic media. The greatest benefit is attained by the addition of approximately stoichiometric quantities of sulfur. Cupric sulflde, rather than metallic copper, is the final discharge product. As a result of the increased power density realized by this innovation, the water‐activated battery constructed for a given power output can be reduced about 15% in weight while the volume is reduced approximately 20%. The effect of sulfur in other similar electrode couples was also investigated.
