METALLIC POROUS BODY HAVING HIGH CORROSION RESISTANCE AND METHOD FOR MANUFACTURING SAME

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 a metal containing at least tin; and a subsequent step of a heat treatment. Such a method can provide a porous metal body in which tin is diffused in a porous nickel body.
