“…3) of nanoconfined samples melt infiltrated at 310°C are obtained by reducing the relative amount of hydride composite to CAS. This can be due to the fact that the main factor affecting nanoconfinement at this temperature is the suitable amount of hydride materials with respect to pore volume of CAS as in our previous work on nanoconfined 2LiBH 4 -MgH 2 [17,18].…”

“…The activation energies are controlled by mechanisms such as slow diffusion processes, inadequate nucleation and infrequent dissociation of the H 2 molecule on the material-gas interface, among others. Considerable advances were made through the application of different approaches and the combination of them: inclusion of several additives with catalytic effect [15][16][17], the use of proper processing techniques [18][19][20] and the application of nanosupports [21][22][23].…”

Several different milling parameters (additive content, rotation velocity, ball-to-powder ratio, degree of filling, and time) affect the hydrogen absorption and desorption properties of a reactive hydride composite (RHC). In this paper, these effects were thoroughly tested and analyzed. The milling process investigated in such detail was performed on the 2LiH-MgB2 system doped with TiCl3. Applying an upgraded empirical model, the transfer of energy to the material during the milling process was determined. In this way, it is possible to compare the obtained experimental results with those from processes at different scales. In addition, the different milling parameters were evaluated independently according to their individual effect on the transferred energy. Their influence on the reaction kinetics and hydrogen capacity was discussed and the results were correlated to characteristics like particle and crystallite size, specific surface area, presence of nucleation sites and contaminants. Finally, an optimal value for the transferred energy was determined, above which the powder characteristics do not change and therefore the RHC system properties do not further improve.

“…[116] By premilling MgH 2 , Gosalawit-Utke et al obtained a MWCNT decorated with TiO 2 15 wt% 6.8 355 [112] dehydrogenation rate approximately twice faster for the nanoconfined sample than that of the sample without MgH 2 premilling. [117] With a self-assembly followed by solution infiltration, Xia et al fabricated a graphene-supported monodispersed 2LiBH 4 -MgH 2 nanocomposite with a particle size of % 10.5 nm. The nanostructuring largely facilitated the physical contact between LiBH 4 and MgH 2 and shortened the mass transport distance, which induced a reversible storage capacity of up to 8.9 wt% at 350 ºC.…”

Lithium borohydride (LiBH4) has been attracting extensive attention as an exemplary high‐capacity complex hydride for solid‐state hydrogen storage applications because of its high hydrogen capacities (18.5 wt% and 121 kg H2 m−3). However, the strong and highly directional covalent and ionic bonds within LiBH4 structure induce high desorption temperatures, slow kinetics, and poor reversibility, which make large‐scale application impractical. To improve its hydrogen cycling performance, several strategies including cation/anion substitution, catalyst doping, reactive compositing, and nanoengineering, have been developed to tailor the thermodynamics and kinetics of hydrogen storage process. For example, largely reduced operation temperatures and remarkably improved hydrogen storage reversibility under moderate conditions have been achieved by the synergistic effect of nanostructuring and nanocatalysis. Herein, the state‐of‐the‐art development of LiBH4‐based hydrogen storage materials is summarized, including the basic physical and chemical properties, the principles of thermodynamic and kinetic manipulation and the strategies to improve hydrogen storage properties. The remaining challenges and the main directions of future research are also discussed.
