Method for Manufacturing Metal-Made Three-Dimensional Substrate for Electrodes, Metal-Made Three-Dimensional Substrate for Electrodes and Electrochemical Applied Products Using the Same

摘要

In a method for manufacturing a metal-made three-dimensional substrate, a metal foil is passed between a pair of rollers 21 and 22 . Each surface S of a pair of the rollers 21 and 22 is provided with protrusion portions 23 arranged in a grid pattern, and the protrusion portions 23 are arranged so that protrusions 23 of the one roller 22 are oriented toward the center 27 of a virtual quadrangle having four adjacent protrusion portions 23a to 23d of the other roller 21 as the apices.
