    Abstract: An organosulfur compound-containing slurry composition for making an electrode. The slurry composition forms an electrode mixture layer that exhibits high adhesion to a current collector even when combined with inexpensive aluminum foil current collector and therefore achieves sufficient capacity. The slurry composition contains an organosulfur compound, a binder, an electroconductive agent, and a solvent and has a pH of 4.0 to 9.0. The slurry composition preferably contains a basic compound. The organosulfur compound is preferably at least one of sulfur-modified elastomer compounds, sulfur-modified polynuclear aromatic compounds, sulfur-modified pitch compounds, sulfur-modified aliphatic hydrocarbon oxides, sulfur-modified polyether compounds, polythienoacene compounds, carbon polysulfide compounds, sulfur-modified polyamide compounds, and sulfur-modified polyacrylonitrile compounds.

    Abstract: Disclosed is an electrode active material that has a large charge discharge capacity, a high initial efficiency, as well as excellent cycle characteristics and rate characteristics and is favorably used in a non-aqueous electrolyte secondary battery. An organo sulfur-based electrode active material contains sodium and potassium in a total amount of 100 ppm by mass to 1000 ppm by mass; an electrode for use in a secondary battery, the electrode containing the organo sulfur-based electrode active material as an electrode active material; and a non-aqueous electrolyte secondary battery including the electrode. Preferably, the organo sulfur-based electrode active material further contains iron in an amount of 1 ppm by mass to 20 ppm by mass. Preferably, the organo sulfur-based electrode active material is sulfur-modified polyacrylonitrile, and the amount of sulfur in the organo sulfur-based electrode active material is 25 mass % to 60 mass %.

    Abstract: The present invention provides a method of producing sulfur-modified polyacrylonitrile, including: a step (1) of heating polyacrylonitrile and elemental sulfur in a rotating-type heating container including a discharge pipe and a sulfur vapor recovery unit while rotating the rotating-type heating container; a step (2) of liquefying a sulfur vapor by the sulfur vapor recovery unit while discharging hydrogen sulfide generated in the heating step; and a step (3) of returning the liquefied sulfur to a mixture of the sulfur and the polyacrylonitrile of the step (1).
