| 摘 要： | 本文研究探讨Ｍｍ合金化对难活化的ＡＢ２型Ｚｒ－Ｍｎ－Ｎｉ系贮氢合金的晶体结构，电化学容量及贮氢电极活化等特性的影响作用。Ｍｍ合金化加入可从根本上改善Ｚｒ系贮氢合金电极的活化性能。这与Ｍｍ合金化对贮氢电极合颗粒表面化学改性作用以及合金颗粒体内微结构改变等因素有关，ＸＲＤ分析表明Ｍｍ合金化后同氢后金晶体结构仍为Ｃ１５相，且其中的Ｃ１４型Ｌａｖｅｓ相含量明显增加，同时，也发现Ｍｍ合金化恶化了贮氢合金电化

| Abstract: | The influence of Mm alloying on the crystalline characteristics,electrochemical capacity and activity of AB2 type Zr-Mn-Ni hydride electrodes was investigated.It was found that Mm alloying managed to activate Mm-containing electrode without any precycling,which meight be attributed to the modification of surface chemical states,the formation of Mmcontaining C14 phase and the change in internal microstructures.However,the cycling stability also was found to be deteriorated in the Mmcontaining hydride electrode because of the chemical activity of Mm atom and its unstable crystalline lattice. |
