Description
次に、本発明においては、（ｂ）成分として、ＡＢ5型ニッケル含有水素吸蔵合金のフッ化処理物を用いるが、このＡＢ5型ニッケル含有水素吸蔵合金としては、Ｌａ1-xＭｍxＮｉ5（ただしＭｍはミッシュメタル、ｘは０≦ｘ≦１の数）、Ｃａ1-xＭｍxＮｉ5（ただしＭｍはミッシュメタル、ｘは０＜ｘ＜１）、ＭｍＭx（ただしＭｍはミッシュメタル、ＭはＮｉ、Ｃｏ、Ｍｎ、Ａｌ、４．５５≦ｘ≦４．７６）、Ｃａ1-xＭｇxＮｉy（ただし、０＜ｘ≦０．２７、３．８≦ｙ≦５．２）、Ｃａ1-xＬａxＮｉ5-(y+z)ＡｌyＣｏz（ただし、０．５≦ｘ≦０．９、０≦ｙ≦０．４、０≦ｚ≦０．４、０＜ｙ＋ｚ≦４）及びこれらの構成金属の一部を他の金属例えばＡｌ、Ｃｅ、Ｃｏ、Ｃｒ、Ｃｕ、Ｆｅ、Ｍｇ、Ｍｎ、Ｍｏ、Ｖ、Ｚｎ、Ｚｒなどから選ばれた少なくとも１種の構成金属以外の金属で置き換えたものがある。これらの水素吸蔵合金についても各金属成分Ａ，Ｂの原子比は必ずしも１：５の整数比になっているとは限らず、±０．３の範囲内で変動している場合があるが、このようなものも本発明において用いることができる。 Next, in the present invention, a fluoride-treated AB5 - type nickel-containing hydrogen storage alloy is used as component (b) . Examples of this AB5 - type nickel-containing hydrogen storage alloy include La1 - xMmxNi5 (where Mm is a misch metal and x is a number in the range of 0≦x≦ 1 ), Ca1 - xMmxNi5 (where Mm is a misch metal and x is a number in the range of 0<x<1), MmMx (where Mm is a misch metal and M is Ni, Co, Mn, Al, 4.55≦x ≦ 4.76), Ca1 - xMgxNiy (where 0<x≦0.27, 3.8≦y≦5.2), and Ca1 -xLaxNi5- ( y+z) AlyCoz (where 0.5≦x≦0.9, 0≦y≦0.4, 0≦z≦0.4, 0<y+z≦4) and alloys in which some of these constituent metals have been replaced with other metals, such as at least one metal selected from the group consisting of Al, Ce, Co, Cr, Cu, Fe, Mg, Mn, Mo, V, Zn, and Zr. In these hydrogen storage alloys, the atomic ratio of the metal components A and B is not necessarily an integer ratio of 1:5, and may vary within a range of ±0.3. However, such alloys can also be used in the present invention.
