ABSTRACT:
A process for preparing a porous metallic body comprising the steps of: rendering a porous resin body electrically conductive, electroplating the conductive resin, and heating the electroplated resin to remove the resin, wherein the step of rendering the resin electrically conductive is conducted by coating the resin with a coating composition containing amorphous carbon particles as a conductive material. In the process, substantially spherical carbon particles may be used as the conductive material. The substantially spherical carbon particles are still preferably amorphous carbon. The thus obtained porous metallic body has reduced defect and more smooth skeleton in the porous body, is less likely to cause stress concentration upon application of bending and tensile force, has lower carbon content, and superior mechanical strength, and, therefore, the substrate is suitable as an electrode substrate for batteries.
