摘要： Provided are a porous metal body that is excellent in terms of corrosion resistance and that is suitable for a collector for batteries such as lithium-ion batteries, capacitors, or fuel cells; and methods for producing the porous metal body. A production method includes a step of coating a porous nickel body with an alloy containing at least nickel and tungsten or a metal containing at least tin; and a subsequent step of a heat treatment. Another production method includes a step of forming a nickel-plated layer on a porous base and then continuously forming an alloy-plated layer containing at least nickel and tungsten or tin, a step of removing the porous base, and a step of reducing metal. Such a method can provide a porous metal body in which tungsten or tin is diffused in a porous nickel body or a nickel-plated layer.

摘要： An electrode active material for capacitors contains a porous carbon material. The porous carbon material has a BET specific surface area of 800 m2/g or more. An X-ray diffraction image of the porous carbon material with CuKαrays has a peak Pk at 2θ=40° to 50°, and the peak Pk includes a component of a peak Pd111 attributed to a (111) plane of diamond crystals. When the X-ray diffraction image has a peak PG002 attributed to a (002) plane of graphite, a ratio of an intensity IG002 of PG002 to an intensity Ik of Pk (IG002/Ik) is 3.0 or less.

摘要： The invention offers an aluminum-plating apparatus that can satisfactorily form an aluminum plating even on the surface of a base body that has a surface on which an insulating or poorly conductive metal oxide film or the like is formed. The aluminum-plating apparatus electrodeposits aluminum onto a base body by conveying the base body in a plating bath. The plating bath is divided into a first electrolysis chamber and a second electrolysis chamber by a partition plate in this order from the upstream side in the conveying direction for the base body. In the first electrolysis chamber, a negative electrode provided in the chamber is electrically connected with the base body such that the base body acts as a positive electrode. In the second electrolysis chamber, a positive electrode provided in the chamber is electrically connected with the base body such that the base body acts as a negative electrode.
