Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
2LiBH 4 /MgH 2 system is considered as one of the prominent high capacity hydrogen storage materials. However, its absorption/desorption kinetics has to be further improved for the practical application. In this paper, we investigated the effects of NbF 5 addition by ball milling on the de/rehydrogenation properties of 2LiBH 4 /MgH 2 system. The results show that NbF 5 additive can lower the desorption temperature and improve the reaction kinetics of 2LiBH 4 /MgH 2 system effectively. The 2LiBH 4 + MgH 2 + 0.05NbF 5 composite exhibits a good cycling de/rehydrogenation property. In first 15 cycles, the average hydrogen absorption and desorption capacities of the composite are about 8.97 and 8.33 wt %, respectively. Desorption thermal analysis indicates that the activation energies of 2LiBH 4 + MgH 2 + 0.05NbF 5 composite are 100.3 kJ/mol for first decomposition reaction and 127.5 kJ/mol for second decomposition reaction. The possible mechanism of the effects of NbF 5 additive for the improved de/rehydrogenation properties of 2LiBH 4 /MgH 2 system is also discussed.
