Summary: In this work, Li3VO4@LiVO2 was introduced into the Mg(NH2)2-2LiH system to enhance the hydrogen absorption and desorption kinetic characteristics. The addition of 10 wt% Li3VO4@LiVO2 greatly improved the hydrogen storage properties, with significant increase in hydrogen absorption and desorption rates, and decrease in the activation energy of hydrogen desorption. Moreover, Li3VO4@LiVO2 also increased the hydrogen absorption and desorption capacities of the sample.

Summary: Li-Mg-N-B-H/ZrCoH3 composites were synthesized by ball milling under different atmospheres. The composite synthesized under hydrogen atmosphere displayed the best hydrogen storage properties. The microstructures and elemental distributions were characterized and it was found that Mg underwent in situ hydrogenation and ZrCoH3 particles were homogeneously distributed. The activation energy of the composite was calculated and found to be lower with the addition of ZrCoH3. The weakening of N-H bond was analyzed and discussed.

Summary: Multiple Ti and Li atom doped carbon nanorings were studied for hydrogen storage using density functional theory. The results showed that both Ti and Li doped carbon nanorings were thermodynamically stable and more stable than undoped carbon nanorings. Metal clustering, which reduces hydrogen storage capacity, was not observed in the doped nanorings. The Ti doped carbon nanoring was found to be suitable for hydrogen storage at low temperatures and high pressures, while the Li doped carbon nanoring was not suitable. The hydrogen desorption temperatures for the Ti and Li doped nanorings were 450 K and 113 K respectively, indicating stronger interaction between H2 molecules and Ti doped carbon nanoring.

Summary: The hydrogen sorption performances of the 4MgH(2) + LiAlH4 system destabilized with 5 wt% Al2TiO5 showed significantly improved dehydrogenation temperature and kinetics. The introduction of Al2TiO5 resulted in earlier hydrogen liberation and enhanced absorption and desorption kinetics, indicating a synergistic effect on hydrogen storage behavior.

Summary: The article summarizes the research progress on the use of LiBH4 and Mg(BH4)2 as hydrogen storage materials and solid-state electrolytes, and proposes effective strategies to improve their performances. It discusses the changes in the phase, structure, and thermal properties of Li/Mg-based borohydrides induced by methods such as milling, ion substitution, coordination, adding additives/catalysts, and hydrides. The similarities and differences between the strategies used for the two applications are also discussed. This review provides insights into the future development of Li/Mg-based borohydrides for hydrogen storage and solid-state electrolytes.

Summary: A one- and three-dimensional coupled model considering the impact of oil velocity and temperature on the internal heat and mass transfer during the hydrogen desorption process was developed to simulate the large-scale oil-heating type Mg-based hydrogen storage tanks. The simulation results showed that the oil velocity has a significant impact on the hydrogen desorption performance, and a recommended oil velocity of 4 m/s was identified.

Summary: This study investigates the adsorption and interaction mechanisms of Li cations on sumanene and triazasumanene surfaces using theoretical methods. It was found that Li+ can be favorably adsorbed on both molecules, with greater interaction energy observed for sumanene compared to triazasumanene. Both materials can uptake hydrogen molecules, with triazasumanene showing a higher capacity. The Li+-decorated triazasumanene complex has potential as a promising hydrogen storage system.

Summary: This study reviewed the recent developments in the hydrogen storage performance of magnesium hydride (MgH2) and its composite system with lithium alanate (LiAlH4) (Mg-Li-Al). The concept of destabilization has been extensively explored and proved effective in reducing desorption temperature and improving sorption properties. The intermetallic alloys formed during the dehydrogenation process provide thermodynamic and kinetic destabilization in the Mg-Li-Al system.
