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).

Abstract: Disclosed is a sulfur-based electrode active material with which a nonaqueous electrolyte secondary battery that has a large capacity and exhibits less deterioration of the cycle characteristics can be obtained even when an electrode is employed in which the sulfur-based electrode active material is used as an electrode active material and an aluminum foil is used as a current collector. Also disclosed is a method for producing an organosulfur electrode active material, including a step of obtaining an organosulfur compound by heat-treating an organic compound and sulfur and a step of treating the organosulfur compound with a basic compound. The organosulfur compound is preferably sulfur-modified polyacrylonitrile, and the basic compound is preferably ammonia. The organosulfur compound may be treated with the basic compound after the organosulfur compound is ground, or may be ground in a medium that contains the basic compound.

Abstract: An encapsulated agent includes a central part and an outer part that covers a surface of the central part. The central part contains a viscosity-reducing material that reduces viscosity of a fluid to be used in a hydrofracturing technique. The outer part contains a plurality of particulate substances and a holding material that holds the plurality of particulate substances and enables gradual release of the central part in the fluid. The outer part involves distribution of the plurality of particulate substances that allows a content to have one or more local maxima in a direction away from the central part.

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 %.
