PURPOSE:To improve a discharge characteristic especially the flatness of discharge voltage of an organic solvent cell, by using an iron disulfide dust, that is, iron sulfate, as the active material to form at least a part of positive electrode surface. CONSTITUTION:A positive electrode is prepared by the method, in which a dust of FeS2 conventionally used as the active material is suspended to aqueous solution of iron sulfate and then dried to adhesively attach the iron sulfate partly to an FeS2 surface, or the method, in which heat treatment of the dust of FeS2 is performed in air or oxygen gas to partly dissolve the FeS2 surface and obtain the iron sulfate, or the like. In this way, an organic solvent cell, in which flatness of discharge voltage can be improved further with a long discharge duration time and an excellent discharge characteristic, can be obtained. |
