<p>According to this invention, part or the whole of elementary Zr as a starting material for producing alloy is substituted by ferrozirconium (Zr-Fe alloy) or zircalloy (Zr-Sn alloy) in order to obtain a hydrogen-occlusion alloy at a reduced raw material cost and a reduced manufacturing cost, maintaining good operation efficiency, high reliability and safety in operation. The alloy is homogeneous without segregation and, hence, is featured by very good properties specific to the hydrogen-occlusion alloy such as amount of hydrogen occlusion, reaction rate and electrode reaction efficiency in the electrolyte. Using the alloy obtained by this method, furthermore, it is possible to provide a nickel-hydrogen storage cell which has a large electric capacity, can be quickly charged and discharged, has a long life and is advantageous in economy.</p> |
