| 简介 |
This invention provides a hydrogen storing alloy and a production method thereof. The hydrogen storing alloyhas a chemical composition of a general formulaR (1-x) Mg x Ni y , wherein R is one or more elements selected from rare earth elements comprising Y, x satisfies 0.05‰¤x‰¤0.3, and y satisfies 2.8‰¤y‰¤3.8. The ratio of the maximal peak intensity present in a range of 2¸=31°-33° to the maximal peak intensity present in a range of 2¸=41°-44° is 0.1 or less (including 0), as measured by X-ray diffraction in which a Cu-K± ray is set as an X-ray source. |
