Figure 8

Influence of cycle-life-time and TiMn2 additives on the morphological characteristics of the powders. The cycle-life-time of the last 200 h for (a) nanocrystalline MgH2 powders, and (b) nanocomposite MgH2/5 wt.% TiMn2 powders. The FE-SEM micrographs of the powders obtained after completion the cyclic hydrogenation tests displayed in (a,b) are shown in (c,d), respectively. STEM-DFIs of the powders obtained after completion 275 h cycle-life-time (MgH2 powders) and 1400 h (MgH2/5 wt.% TiMn2 powders) are shown in (e,f), respectively.
