Abstract
The present invention relates to a method for readily producing an anode for rechargeable batteries having conflicting properties in good balance, including the corrosion resistance and the activities such as the initial activity and the high rate discharge performance, and having excellent recyclability. The method includes the steps of mixing and molding anode materials containing an electrically conductive material and at least two kinds of AB5 type hydrogen storage alloys, wherein said alloys have substantially single phase structures and the same composition, wherein each of the alloys have an average crystal long axis diameter of 30 to 350 μm, and wherein the alloys have different ratios (D1/D2) of the average crystal long axis diameter (D1) to the average short axis diameter (D2).
