Abstract: A device for producing an electrode laminate includes a roller configured to press an active material layer-attached current collector layer including a current collector layer and an active material layer disposed on at least one surface of the current collector layer. A diamond-like carbon film having an average roughness of 0.16 μm or less is on a surface of the roller in contact with an active material layer or a press sheet is disposed between the roller and a surface of the active material layer, and a diamond-like carbon film having an average roughness of 0.16 μm or less is on a surface of the press sheet in contact with the active material layer.

Abstract: A method of producing an all-solid battery includes pressing a laminate in a state where the laminate is insulated from a press machine. The laminate includes a negative electrode current collector layer, a negative electrode active material layer, a solid electrolyte layer, and a positive electrode active material layer. The negative electrode current collector layer includes copper, at least one of the negative electrode active material layer and the solid electrolyte layer includes a sulfide solid electrolyte, and the press machine is an anisotropic press machine.

Abstract: There is provided a surface treatment method in which a processing gas is brought in contact with a heated processing object made of steel, an element in the processing gas is solid-solutionized, and thus a surface treatment is performed on the processing object. The processing object is heated to a heating temperature in a vicinity of a processing temperature at which the surface treatment is performed by heating an atmosphere in which the processing object is disposed. The surface treatment is performed by bringing the processing gas in contact with a surface of the processing object while the processing object which is heated is directly heated to the processing temperature.
