| 摘 要： | 以普通Al粉、LiAlH4和Li3AlH6作为Al源，分别与LiBH4进行球磨复合，通过对LiBH4/Al、LiBH4/LiAlH4和LiBH4/Li3AlH6复合物吸放氢过程的物相分析、放氢性能分析和吸氢性能分析，系统研究不同Al源对LiBH4储氢性能的影响，发现Li3AlH6分解提供的活性Al促进LiBH4放氢作用明显，并且其放氢产物的可逆吸氢动力学性能也最好。

| Abstract: | In this paper ,LiBH4 was ball-milled respectively with Al powder ,LiAlH4 and Li3AlH6 as the Al source to form hydrogen storage composites .T he effects of Al source on the hydrogen storage proper-ties of LiBH4 were systematically investigated by phase analysis of hydriding/dehydriding process and hy-drogen desorption/absorption properties measurements of LiBH4/Al ,LiBH4/LiAlH4 and LiBH4/Li3 AlH6 composites .It was found that the active Al formed by decoposition of Li3AlH6 showed eminent improve-ments on the hydrogen decomposition of LiBH4 ,and its dehydrided product showed the best reversible hy-driding kinetics . |
