Fig. 11. (a) Hydrogenation/dehydrogenation cycle-life-time test of nanocomposite MgH₂/10 wt% MG-Ti₂Ni strip samples, conducted at 225 °C under 10 bar (uptake) and 200 mbar (release) to cover 84 continuous cycles within 30 h. (c) BFI and (c) corresponding NBDP of the sample after completion of 84 cycles. For comparison, the PCT/cycle-life-time test of pure MgH₂ obtained after 6 h of RBM is displayed in (d). A low magnification BFI image of pure MgH₂ after complete of PCT test is presented together with related NBDP in (e) and (f), respectively.
