Abstract
Process of making high purity, synthetic FeS, and an electrochemical battery employing such synthetic FeSin the positive electrode. Synthetic FeSmay be prepared by a sulfidation process comprising reacting ferric oxide, hydrogen sulfide, and elemental sulfur at a temperature above the melting point of element sulfur. Synthetic FeSmay also be produced by a milling process that comprises (i) milling iron powder and sulfur powder in the presence of a milling media and a processing agent to provide a homogenous powder mixture, and (ii) treating the powder mixture to form FeS. In the milling process, the powder mixture may be treated to form FeSby heating the powder mixture or subjecting the powder mixture to a subsequent milling operation.
