PURPOSE:To improve a discharge characteristic easpecially the flatness of discharge voltage of an organic solvent cell, by using a dust of iron disulfide, that is, a mixture of iron sulfate and iron oxide as the active material to form at least a part of a 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 an aqueous solution of iron sulfate and then dried and oxidized to adhesively attach a mixture of iron sulfate and iron oxide to a part of an FeS2 surface, or the method, in which heat treatment of the dust of FeS2 is performed in air or oxidizing gas to partly dissolve the FeS2 surface to obtain the mixture with 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. |
