Summary: The role of mass transport for bubble generation reaction in FA dehydrogenation has been overlooked for a long time, limiting the TOF values of most catalysts to less than 1000 h(-1). By proposing a design principle of efficient catalyst with synergism of highly active catalytic components and developed porous structure for effective mass transport, a Pd60Au40/HPC-NH2 catalyst with ultrasmall nanoparticles has been developed, exhibiting TOF values up to 3763 h(-1) at room temperature and 29,210 h(-1) at 323 K.

Summary: This study found that the coordination between Li+ and solvents determines the anodic stability of localized high-concentrated electrolytes (LHCEs) on high-voltage cathodes, which can be finely tuned by ambient diluents. Among the possible diluents, 2H,3H-decafluoropentane (HFC) was found to satisfy the principle of weak but sufficient interactions, which enhances Li+ coordination and offers excellent antioxidant chemistry. The study provides guiding principles for improving the cathodic and anodic stability of electrolytes, benefiting the development of LHCEs and inspiring next-generation lithium batteries formulation.

Summary: In this study, three series of alloys were prepared and their crystal structural characteristics and hydrogen storage properties were investigated. The results showed that a single C14-Laves phase with homogeneous element distribution existed in all alloys. The hydrogen absorption/desorption plateau of the alloys increased as the Fe, Mn, or Ti content increased. The hydrogen storage capacity of the alloys also correlated negatively with the hydrogen affinity of interstitial sites. Ti0.935Zr0.085Cr1.3Mn0.3Fe0.4 alloy exhibited saturated hydrogenation under 8 MPa at 293 K and dehydrogenation around 24.91 MPa pressure at 363 K with a hydrogen capacity of 1.74 wt%, as well as excellent cycling performance and mere hysteresis. Ti0.92Zr0.10Cr1.0Mn0.6Fe0.4 alloy showed promising hydrogen capacity of 1.86 wt% at 283 K and a dehydrogenation pressure of 27.94 MPa at 363 K, along with satisfactory cycling durability. This study can guide the compositional design of AB2-type hydrogen storage alloys for hydrogen compression application.

Summary: Due to the environmental pollution and thermal risks of lithium-ion batteries, it is necessary to recycle and assess the safety of spent lithium-ion batteries. In this study, lithium tin alloys (LixSny) were prepared via mechanical alloying to simulate the tin anode materials at different lithium-embedded states. The Li22Sn5 alloy exhibited the best hydrolysis performance, releasing 351 mL g-1 of hydrogen in 10 seconds at 293 K. Safety evaluation was conducted based on hydrolysis performance, maximum adiabatic temperature rise, and other parameters. The study also demonstrated the controllable reaction rates by tailoring the solution components, enhancing the security and controllability for practical application. Furthermore, the hydrogen production of Li22Sn5 sample increased to 624 mL g-1, even at a subzero temperature of 243 K, generating 510 mL g-1 of hydrogen within 30 seconds. This research provides a novel approach for the safety evaluation and recycling of tin anode materials in spent lithium-ion batteries.

Summary: Ultrafine carbon-encapsulated NbC nanoparticles were synthesized using the carbon thermal shock method. The MgH2-10 wt% NbC/C composites exhibited excellent low-temperature hydrogen storage performance, with a lower onset dehydrogenation temperature compared to MgH2-10 wt% NbC and undoped MgH2. The enhanced hydrogen storage performance was attributed to the electron transfer process, refinement of MgH2 particles by NbC nanoparticles, and destabilization of the Mg-H bond caused by carbon substrate.
