Summary: This study provides insights into the active catalytic species in ceria additive loaded hydrogen storage system, MgH2, through mechanical milling and cycling tests. In-situ X-ray diffraction and Raman spectroscopy studies confirm the interaction between MgH2 and CeO2, with evidence of reduced cerium oxides throughout the interactions. The CeHx/CeOx interfaces play a key role in suppressing the formation of MgO rock salt.

Summary: The influences of microstructure evolution induced by thermal-mechanical processing on the hydrogen storage performance of Mg-Ni-Gd-Y-Zn-Cu alloys were investigated. The extruded alloy showed higher hydrogen absorption capacity and faster hydrogen ab/desorption kinetics due to refined alpha-Mg grains and the presence of 14H-type LPSO phases. These findings have implications for the design and manufacturing of magnesium-based hydrogen storage materials.

Summary: This study presents a systematic investigation of the interactions between hydrogen and Mg-Ag alloys prepared by mechanical alloying. The alloys were found to be effectively synthesized with mechanical alloying, extending solubility limits compared to known phase diagrams. Further annealing enhanced synthesis to obtain well crystallized samples that could absorb significant amounts of hydrogen. Magnesium hydride and AgMg intermetallics were formed as residual products that did not react with hydrogen under the chosen conditions. Samples characterized directly after ball milling showed higher reaction kinetics with hydrogen.

Summary: This study shows that the dehydrogenation activation energy of MgH2 can be lowered by incorporating ceria, but the ceria undergoes phase transformations during dehydrogenation. It also suggests that reduced cerium oxide phases may be mistaken as cerium hydrides, therefore the belief in CeH2 as an active catalyst in the MgH2/CeO2 hydrogen storage system needs further scrutiny.

Summary: In this paper, the interactions between mechanically alloyed Mg6Pd1-xAgx alloys and hydrogen were studied. The structures of the alloys were analyzed using X-ray diffraction (XRD), which confirmed the presence of a single Mg6Pd-type phase for samples with up to x=0.5 silver concentration. The kinetics of hydrogenation process and the properties of synthesized hydride were investigated using a Sievert-type sorption analyzer and differential scanning calorimetry (DSC) with thermogravimetric analysis (TGA). The results showed that partial substitution of palladium with silver improved the hydrogen sorption kinetics compared to pure Mg6Pd intermetallic phase, but resulted in lower hydrogen content. The influence of silver on the decomposition kinetics was also observed.

Summary: This study parameterized, experimentally validated, and applied a model to accurately simulate the absorption and desorption processes in a double-layered annulus metal hydride tank. The results showed that the hydrogen absorption performance can be enhanced by increasing initial porosity and decreasing initial particle radius, temperature, and hydrogen concentration. On the other hand, hydrogen desorption performance mainly depends on increasing the hydrogen concentration.

Summary: Considering the challenges in cathode materials for aluminum-ion batteries, V6O13 is proposed as a promising candidate for the first time with the help of density functional theory calculations. It is found that aluminum ions can be reversibly stored in V6O13 through intercalation reactions, providing a high discharge voltage plateau. The use of a pre-lithiation strategy further improves the redox kinetics and leads to higher capacity and energy density. Additionally, the research reveals the shielding effect of pre-inserted Li and the accelerated diffusion rate at the atomic scale.

Summary: In this work, an ultra-stable electrode-solid electrolyte composite for high-performance all-solid-state lithium-ion batteries (ASSLIBs) is fabricated by uniformly covering each MgH2 nanoparticle with ultrathin Mg(BH4)(2) layers on the surface of graphene. The presence of Mg(BH4)(2) layers enhances the Li ion conductivity of the graphene-supported MgH2 nanoparticles, resulting in uniform stable interfaces with high ionic and electronic conductivity. Additionally, the stable framework of inactive Li2B6 and the structural support of graphene alleviate volume change and facilitate intimate contact, leading to an ultrahigh specific capacity of 800 mAh g(-1) for MgH2 after 350 cycles at 2 A g(-1).

Summary: This study reports a new strategy of utilizing water-contained VOPO4·H2O to enhance Al3+ migration in Al ion batteries. It is revealed that VOPO4·H2O has a water lubrication effect and smaller steric hindrance, resulting in high capacity and fast Al3+ diffusion. However, the instability of water leads to rapid performance degradation. To solve this problem, ultrathin VOPO4·H2O@MXene nanosheets were fabricated to improve the cycling stability. The VOPO4·H2O@MXene composite delivers high discharge potential and maintains discharge capacities after cycling. This work provides new insights into water-contained AIBs cathodes and guidance for developing high-performance AIBs.

Summary: In this study, V6O13 nanobelts with a thickness of 11 nm were fabricated to improve the reversible hydrogen storage performance of MgH2. The interaction between V6O13 nanobelts and MgH2 resulted in the in situ homogeneous formation of metallic V during the initial dehydrogenation of MgH2. The catalysis of metallic V decreased the energy required for H2 desorption from MgH2 and improved the hydrogen storage capacity, with 6.8 wt% capacity retained after 10 cycles at 250 degrees C.
