Summary: Building liquid channels in magnesium hydride by introducing lithium borohydride ion conductors improves its low-temperature hydrogen sorption. For example, 5 wt% LiBH4-doped MgH2 can release about 7.1 wt.% H-2 within 40 min at 300 degrees C, while pure MgH2 only desorbs less than 0.7 wt.% H-2. Additionally, the LiBH4-doped MgH2 exhibits faster desorption kinetics with more than 10 times enhancement compared to pure MgH2, and maintains a stable cyclic performance even after six absorption and desorption cycles. This approach provides insights for promoting hydrogen absorption and desorption of other metal hydrides.

Summary: We designed and synthesized a porous organic polymer (POP) with a conjugated and hierarchical structure, which exhibited excellent electrochemical properties as an anode material for sodium-ion batteries (SIBs). Through combined experiments and theoretical computation, we revealed the Na-storage mechanism and dynamic evolution processes of the POP, including a 12-electron reaction process with Na and stable composition and structure evolution during repeating sodiation/de-sodiation processes. This quantitative design for ultrafast and highly durable sodium storage in the POP could benefit the rational design of organic electrode materials with ideal electrochemical properties.

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: High operating temperatures and sluggish kinetics are obstacles for the practical application of MgH2 as a solid hydrogen carrier. This study investigates the catalytic activity of nanostructured niobium oxide (Nb2O5) and explores the relationship between nanoparticle size, morphology, and catalytic activity. The results demonstrate that the primary particle size is the decisive factor in the catalytic activity of Nb2O5, enabling dehydrogenation at low temperatures and higher reactivity due to the formation of more uniform and finer Nb-based active species when ball-milled with MgH2.

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.
