    摘要： The invention relates to a new method of manufacturing a sealed rechargeable alkaline battery including metal oxides as positive electrode active materials and a hydrogen absorbing alloy as a negative electrode material. The basic principle of the method is that, instead of the conventional electrochemical formation, the property of a hydrogen absorbing alloy is utilized to cause the negative electrode to absorb hydrogen to thereby achieve precharged portions within the negative electrode having a relatively larger capacity as compared with the positive electrode. Regardless of the kind of positive electrode, the method of the invention insures a broad freedom in the capacity appropriation between the positive and negative electrodes.

    摘要： The present invention provides a method of producing a hydrogen storage alloy low in cobalt content which can restrains a decrease in cycle life characteristic and preservation characteristic of an alkaline storage battery when the alloy is used as a negative electrode. The method includes the following steps. An Mm-Ni system hydrogen storage alloy which has a crystal structure of CaCu.sub.5 and contains 15 atom % or less of cobalt is powdered to have an average particle diameter of 10-100 .mu.m. Then, the powdered alloy is immersed in a treatment solution at 80.degree.-130.degree. C., the treatment solution comprising an alkaline aqueous solution containing 10 g/l or more of lithium hydroxide and having a specific gravity of 1.1 or higher, and cobalt ions which is contained in the alkaline aqueous solution, thereby forming a layer containing nickel and cobalt in higher concentration than in the bulk of the powdered alloy onto the alloy surface.

    摘要： 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.
