    摘要: An electrode excellent in high-rate discharge characteristics is provided by increasing the adhesive strength of the conductive core material (3) to the sintered nickel porous body which form the sintered type substrate. The electrode of the present invention uses a sintered type substrate containing a part wherein the diameter of the skeleton forming the sintered nickel porous body becomes smaller from the joining interface of the conductive core material toward the substrate surface. The region wherein the skeleton (1) is thicker than in other parts preferably ranges within about 1/5 of the substrate thickness starting from the both surfaces of the core material toward the outsides.

    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 5 and contains 15 atom% or less of cobalt is powdered to have an average particle diameter of 10-100 µm. Then, the powdered alloy is immersed in a treatment solution at 80-130°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.
