| description | A substrate for secondary cells which is produced by forming a porous metal layer on a metal base by sintering and has such an excellent adhesion to the base that the sintered porous metal body does not separate nor come off from the base when the substrate is wound into a cylindrical battery. A metal layer having a melting point lower than that of the base is formed on at least one side of the base and a metal powder layer which has a melting point higher than that of the metal layer is formed on the metal layer, and then, sintering the metal powder at a temperature higher than the melting point of the metal layer and lower than the melting points of the base and the metal powder. Alternatively, at least one side of the base is boronized and a layer of powder of metal which forms an eutectic alloy with boron is formed on the boronized surface. Next the metal powder is sintered at a temperature higher than the melting point of the eutectic alloy and lower than the melting points of the base body and metal powder, thus forming a porous layer. |
