ABSTRACT:
In the method of the present invention for producing a hydrogen-storing alloy, part or whole of single substance of Zr as a starting material is replaced with a ferrozirconium or a zircalloy. This method enables production of a hydrogen-storing alloy at reduced material and production costs and with high efficiency and safety of work. The alloy produced by this method has high homogeneity with no segregation. It is thus possible to obtain a hydrogen-storing alloy superior in hydrogen-storing characteristics such as hydrogen storage capacity, reaction speed, and electrode reaction efficiency in an electrolyte. It is also possible to obtain, by using this alloy, a nickel-hydrogen storage battery having a large storage capacity and capable of performing quick charging and discharging, while exhibiting longer life and higher economy.
