PORÖSER METALLISCHER KÖRPER MIT HÖHER SPEZIFISCHER OBERFLÄCHE, VERFAHREN ZU DESSEN HERSTELLUNG, PORÖSES METALLISCHES MATERIAL UND ELEKTRODE FÜR ALKALISCHE SEKUNDÄRBATTERIE |
摘要 |
A porous metallic body that has a three-dimensional reticular skeleton structure wholly constituted of a powdery metallic sinter with a porosity of 10-60 % and that has a total porosity of 80-99 %. The specific surface are thereof is as large as, for example, 300-11,000 cm<2>/cm<3>. This body can be reinforced with reinforcing plates and is suitable as an electrode of a alkaline secondary battery capable of attaining a long service life and a large capacity of active materials which can be contained. The metallic body is produced by molding a foamable slurry containing a metallic powder, drying the molded slurry preferably after foaming, and sintering the same. <IMAGE> |
