MANUFACTURING METHOD OF METALLIC POROUS BODY HAVING HIGH CORROSION RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a metallic porous body having excellent heat resistance and corrosion resistance such as electrolysis resistance, and suitable for batteries, such as lithium-ion batteries, capacitors and current collectors of a fuel cell.

SOLUTION: The manufacturing method of the metallic porous body comprising at least nickel and tungsten includes: a step of coating a nickel porous body with an alloy containing at least nickel and tungsten; and a step of performing heat treatment thereafter and diffusing the tungsten into the nickel porous body.
