Abstract
A method for manufacturing a hydrogen absorbing alloy including, comprising the steps of (a) causing a punched metal sheet to run in a slurry of hydrogen absorbing alloy powder, to thereby cause the slurry to be adhered onto the punched metal sheet, the punched metal sheet having a plurality of apertures arranged in a staggered fashion; (b) drying the punched metal sheet on which the slurry has been adhered, to thereby obtain an electrode sheet; (c) cutting the electrode sheet into electrode sheet fragments, each electrode sheet fragment having a first axis and a second axis perpendicular to the first axis, and each electrode sheet fragment having aperture-formed portions and aperture-non-formed portions therein; (d) rolling an electrode sheet fragment in a rolling direction parallel to the first axis of the electrode sheet fragment, the electrode sheet fragment having an aperture array arrangement such that any given line running along the electrode sheet fragment parallel to the second axis of the electrode sheet fragment will intersect aperture-formed portions therein; and (e) coiling the thus rolled electrode sheet fragment in a coiling direction which is the same as the rolling direction.
