Low temperature metal/sulfur battery with anode of an elemental sulfur and iron(II) sulfide mixture

摘要

A low temperature metal/sulfur battery has an anode comprising elemental sulfur, mixed or fused with iron (II) sulfide powder, which is reduced directly to sulfide ions. A low temperature metal/sulfur battery has a separator for separating a novel positive pole (cathode) side from a conventional negative pole (anode) side comprising an anode of e.g. zinc, aluminum, sodium, lithium or their alloys and an anolyte of caustic potash, caustic soda, sodium chloride or ammonium chloride solution or, when sodium or lithium is used, an organic solvent or solid electrolyte. The cathode side comprises elemental sulfur which contains iron (II) sulfide powder in suspension or fused with the sulfur and which is reduced at an iron (II) sulfide or iron electrode at -30 to +60 deg C in an aqueous caustic soda or potash solution mixed with sodium chloride to allow current flow from the anode to the cathode.
