中国科学院大连化学物理研究所的研究人员在储氢材料研究方面取得新进展,通过多组分氢化物复合,显著改善了Mg(NH_2)_2-LiH储氢材料的吸脱氢热力学和动力学性能,实现了100℃以下可逆吸脱氢。在此前研究人员设计的金属氨基化合物储氢体系中,Mg(NH_2)_2-LiH材料具有较高的储氢容量和较好的可逆性,被认为是最具车载实用前景的储氢材料之一。但该体系需要较高的吸氢温度(150℃)和放氢温度(180℃),利用燃料电
Researchers at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, made new progress in the study of hydrogen storage materials. The thermodynamic and kinetic properties of dehydrogenation of Mg (NH_2) _2-LiH hydrogen storage materials were significantly improved by multi-component hydride compound , To achieve a reversible dehydrogenation below 100 ℃. Mg (NH_2) _2-LiH has the highest hydrogen storage capacity and good reversibility in the hydrogen storage system of metal amide compounds previously designed by researchers, which is considered as one of the most promising hydrogen storage materials . However, the system requires a higher hydrogen absorption temperature (150 ° C) and a hydrogen release temperature (180 ° C)
