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金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合金化后贮氢合金主相晶体结构仍为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的电化学循环寿命性能。
In this paper, the effect of Mm alloying on the crystal structure, electrochemical capacity and activation of hydrogen storage electrode in AB2-type Zr-Mn-Ni hydrogen storage alloys was investigated. Mm alloying can fundamentally improve the Zr-based hydrogen storage alloy electrode activation performance. This Mm alloying on the hydrogen storage electrode alloy particle surface chemical modification and the alloy particles in vivo changes in microstructure and other factors. XRD analysis showed that the main phase structure of Mm alloy was still C15 phase and the content of C14 Laves phase increased obviously. At the same time, it was also found that Mm alloying deteriorates the electrochemical cycle life performance of the hydrogen storage alloy.
