METHOD OF MANUFACTURING A POROUS METALLIC SHEET FOR USE AS AN ELECTRODE SUBSTRATE OF A BATTERY

摘要

The present invention relates to a method of manufacturing a porous metallic sheet for use as an electrode substrate of a battery. The method comprises the steps of placing a web comprising metallic fibers on a supporter and injecting fluid having a high pressure and a high speed into the web to intertwine the metallic fibers with each other to form the metallic fibers into a three-dimensional sheet. The method further includes the step of heating the three-dimensional sheet comprising intertwined metallic fibers at a pressure and at a temperature lower than the melting point of the metallic fibers so as to fuse surface of the metallic fibers at points of intersection.
