摘要
Mg-Ni系贮氢合金虽储氢量高,但放氢温度高、吸放氢动力学性能差,限制了合金的广泛应用。为克服Mg-Ni系贮氢合金的这些缺点,开发贮氢量大、吸放氢性能好的贮氢合金,采用各种方法对合金进行改性。为进一步了解Mg-Ni系贮氢合金方面的研究进展,调研了国内外在Mg-Ni系贮氢合金改性方面研究进展,主要从合金表面处理、成分调节以及纳米处理这3个方面进行了阐述。
Mg-Ni-based hydrogen storage alloys have large capacity of hydrogen absorption,but its dehydriding carries out at high temperature and dynamic behavior on hydriding and dehydriding limits its application in more fields.Many works taking different methods have been done in the world to solve these problems and improve its operational performances.The investigation works about improvement on Mg-Ni-based hydrogen storage alloys were reviewed and discussed mainly in the fields of surface treatment,composition changing and nano-treatment.
