Abstract
A non-aqueous primary battery comprised of an electrolytic solution of a solvent and a solute, a separator, an anode, and a bismuth (III) sulfide cathode is provided. The electrochemical system of this invention is particularly useful in small primary batteries commonly referred to as "button cells" due to its high volumetric energy density and retention of cell dimensions.
