Abstract: To provide an electrode for non-aqueous electrolyte batteries, which traps hydrogen sulfide gas, generated from the inside thereof for some reason, in the electrode, and suppresses the outflow of hydrogen sulfide gas to the outside of the battery. An electrode for lithium ion batteries includes a coating material which contains a silanol group and is present on at least a surface of an active material layer. The active material layer contains a sulfur-based material and a resin-based binder. The sulfur-based material is an active material capable of alloying with lithium metal or an active material capable of occluding lithium ions. The coating material containing the silanol group is a silicate having a siloxane bond or a silica fine particle aggregate having a siloxane bond as a component.

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.
