Title:
METALLIC POROUS BODY AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/1998/004374
Kind Code:
A1
Abstract:
A metallic porous body (22) is manufactured by a method comprising the steps of aligning many short metallic fibers (3) by utilizing a magnetic field, holding the fibers (3) on a metallic base plate (9) in a state that the fibers (3) are erected nearly perpendicularly to the surface of the plate (9) with an adhesive (19) supplied to the surface of the plate (9), removing the adhesive by thermal decomposition and, at the same time, joining the fibers (3) integrally with the plate (9) by sintering. An electrode plate (52) is manufactured by using the porous body (22) as a core material and filling the space between fibers (3) with an active material.
