The effect of the vanadium content on the cyclic stability of V-Ti binary alloys was investigated. V1-xTix, x = 0.2 and 0.5 samples were hydrogenated and dehydrogenated at 410 K and 553 K respectively, for more than 100 times. During hydrogen cycling, reduction in the reversible hydrogen storage capacity was clearly observed from both samples. No prominent V-effect was found. In fact, the reduction rates of two samples were similar; both samples showed a similar to 25% reduction in the reversible hydrogen storage capacity after 100 cycles. In addition, the shape of the pressure composition-isotherm (PCT) curves was significantly altered over the testing cycle period; the absorption and desorption plateaus got markedly inclined and the hysteresis became evidently smaller. We found that even after the hydrogen storage capacity of V1-xTix was significantly reduced, at low enough temperature V1-xTix was able to absorb hydrogen as much as it did at the first cycle. Furthermore, the reversible hydrogen storage capacity of V0.8Ti0.2 at 410 K was recovered to a certain degree after hydrogenating the sample at low temperatures.
