Hydrogen absorbing alloy and secondary battery |
| 摘要 |
The present invention provides a hydrogen absorbing alloy containing as a principal phase at least one phase selected from the group consisting of a second phase having a rhombohedral crystal structure and a first phase having a crystal structure of a hexagonal system excluding a phase having a CaCu<SUB>5 </SUB>type structure, wherein a content of a phase having a crystal structure of AB<SUB>2 </SUB>type is not higher than 10% by volume including 0% by volume and the hydrogen absorbing alloy has a composition represented by general formula (1) given below: <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUB>1-a-b</SUB>Mg<SUB>a</SUB>T<SUB>b</SUB>Ni<SUB>Z-X-Y-alpha</SUB>M1<SUB>X</SUB>M2<SUB>Y</SUB>Mn<SUB>alpha</SUB> (1) <?in-line-formulae description="In-line Formulae" end="tail"?>
