Abstract
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.
