    摘要： A battery has elements for electromotive-force accommodated in a metal outer can which has a bottom having a cylindrical, prismatic or similar shape. The ratio of the bottom thickness (TA) the side thickness (TB) is 1.5-7.0. The metal outer can contains primarily iron and a layer of nickel is provided on at least the inner face of the battery. Shallow grooves are formed on the nickel layer perpendicular to the bottom face. An iron-based metallic sheet formed with a nickel layer on at least one face is subjected to drawing forming into a tubular shape having a bottom, continuous ironing processing being performed such that the side of the can formed in the tubular shape has an ironing ratio in the range of 20% to 90% and a metal outer can is thereby manufactured having a ratio of a bottom thickness to its side thickness from 1.5 to 7.0, having a cylindrical shape, prismatic shape or shape similar thereto, and with shallow longitudinal grooves formed in a nickel layer provided on the battery inside face.

    摘要： A battery accommodates elements for electromotive-force within a metal case. This metal case is a metal case having a bottom wherein the bottom thickness/side thickness ratio has a value of 1.2-4.0 and has a cylindrical, prismatic or similar shape. The metal case is constructed of a metal material whose chief constituent is aluminum. Furthermore, it is desirable that a multiplicity of shallow grooves perpendicular to a bottom face are formed in at least a battery inside face of the metal case and moreover that a nickel layer is provided on the battery inside face. The metal case is made by DI processing involving drawing and ironing, to have a value of bottom thickness/side thickness ratio which was hitherto unavailable,i.e., 1.2-4.0 can be obtained.

    摘要： A nickel positive electrode including an active material mixture mainly composed of a nickel oxide and an electrically conductive support, a metal and/or an oxide thereof including elements effective for increasing oxygen overvoltage, preferably at least one element selected from Ca, Ti, Nb, Cr, Y and Yb is contained in a conducting agent such as metallic Co and/or Co oxide added to supplement the electrical conductivity of the active material. By virtue of this construction, the decrease of charging efficiency caused by increase of battery temperature and decrease of the oxygen overvoltage with charging of the battery can be inhibited and the charging efficiency can be improved in a wide temperature atmosphere. Thus, a nickel-metal hydride storage battery of high capacity can be provided.

    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.
