摘要 综述了稀土镁基 AB_3型贮氢电极合金的研究进展。分别从合金结构、热力学、成分及制备方法等方面进行总结,认识到循环稳定性差是 AB_3型贮氢电极合金目前存在的最主要问题,并就如何改善合金循环稳定性的问题进行了讨论。稀土镁基 AB_3型贮氢合金的贮氢量高于传统的稀土基 AB_5型贮氢合金,有望成为新一代的贮氧电极合金材料。 This paper summarizes the development of rare-earth Mg-based AB3-type hydrogen-storage electrode alloys; introduces its structure, the thermodynamic properties, the compositions and the preparation; discusses how to improve the poor cyclic stability,which is considered the greatest obstacle to application of AB3-type hydrogen-storage electrode alloys. The hydrogen storage capacity of hydrogen-storage electrode alloys is much higher than that of conventional ABe-type electrode alloys, and hence AB3-type electrode alloys could be a promising material for electrochemical hydrogen storage.
