FORMATION METHOD OF HYDROGEN ACCUMULATION ACTIVE SUBSTANCE FOR ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a method for forming a hydrogen storage active material for an electrode, whereby the material can be embrittled and crushing is remarkably easy for profitability. SOLUTION: A method for forming a hydrogen storage active material for an electrode produces a bulk active material having a means for reversibly accumulating hydrogen and a homogeneous-phase structure. Next, the bulk material is hydrogenated, dehydrogenated, and crushed to a predetermined grain size distribution.
