Method for manufacturing porous sheet, porous metal sheet manufactured by this method, and electrode for battery

摘要

Metal powders (P) are spread on a feeding belt (2) or a supporting sheet which is continuously fed, the feeding belt or the supporting sheet on which the metal powders have been spread is passed through a sintering oven (4), and the metal powders are sintered, with adjacent uncompressed metal powders in contact with each other partly and gaps present therebetween. Consequently, contact portions of the metal powders are integrated with each other and the gaps are formed as fine pores.
