<p>Disclosed in a wet process for producing a CuS cathode having a high capacity and reduced tendency to induce swelling when incorporated into a cell having a non-aqueous electrolyte and a lithium anode. Elemental copper and sulfur are dispersed in an aqueous HCl solution free of ionic contaminants. After reaction, the resulting cupric sulfide is washed with an aqueous solution of a mixture of, e.g., ammonium chloride and hyrochloric acid, to remove cuprous ions. The product is then washed with water until the chloride ion content of the wash water is less than about 5 ppm. The washed solid product is then dried to subline residual NH4Cl, pressed to form a shape retaining cathode, subjected to a final heat treatment and incorporated into a cell or battery having a lithium metal anode and a nonaqueous electrolyte.</p> |
