摘要： PROBLEM TO BE SOLVED: To improve the productivity at the time of surface treatment for a battery can forming material. SOLUTION: A metal powder is sprayed or applied in pasty state on or to the surface of a hot rolled steel plate (hot coil). Subsequently, annealing and rolling are carried out to form a metallic layer composed of the above metal powder on the surface of the hot rolled steel plate. Then, cold rolling is performed, and the resultant steel sheet is subjected to annealing and to skin pass rolling. Instead of forming the metallic layer by the use of the metal powder as mentioned above, the metallic layer can be formed on the surface of the hot rolled steel plate by means of plating.

摘要： PURPOSE: To manufacture a metallic porous body for a battery electrode substrate comprising metallic fibers, and a plate. CONSTITUTION: A mixture is formed by kneading metal powder having a particle size of 0.1-5μm and a binder. The mixture is extruded from a spinning nozzle to spin metallic fibers having a fiber diameter of 1.0-100μm, then the spun metallic fibers are formed in a porous cloth shape such as a nonwoven fabric a fabric, a knit, and a foamed state, and sintered after removing the binder. Active material is filled in pores of a metallic porous body for an electrode plate to form a plate of a battery. Or without use of the resin binder, metal powder is extruded from the spinning nozzle by applying high pressure to spin metallic fibers.
