Summary: A composite material of 0.71 LiBH4-0.29 NaBH4 and CMK-3 carbon with nanopores was successfully synthesized, showing improved hydrogen absorption-desorption kinetics. After five cycles, the composite maintained a consistent uptake of about 3.5 wt.% H-2. The enhanced kinetics were attributed to carbon-hydride surface interactions and the heat transfer capability of the carbon support. The nanopore confinement may also contribute to the improved reversibility.

Summary: Mixtures of LiAlH4/FeCl2 and LiBH4/FeCl2 were prepared under cryogenic conditions using ball milling, with the optimal production conditions being milling for 30 minutes at -196 degrees C and 15 Hz oscillation frequency. Hydrogen release in LiAlH4/FeCl2 mixtures starts at around 60 degrees C, while LiBH4/FeCl2 mixtures exhibit dehydrogenation starting at 40 degrees C and finishing at about 300 degrees C. The formation of LiCl is considered the driving force behind the decomposition reactions in these reactive mixtures. Cryogenic ball-milling has a positive effect on production and low-temperature dehydrogenation of the studied samples.

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: In this study, the poisoning resistance behaviors and mechanism of ZrCo in H2+CO2 mixed gas were systematically investigated. Even trace amounts of CO2 can strongly deteriorate hydrogenation kinetics of ZrCo, but this phenomenon can be mitigated by further increasing the inputting pressure of the mixed gas. In-situ surface reconstruction strategy by high-temperature treatment was proposed, which enhanced the CO2 poisoning tolerance of ZrCo through the formation of metallic Co nanoclusters on ZrCo surface.

Summary: Metal borohydrides have high theoretical hydrogen production/storage densities and offer efficient real-time hydrogen supply for electronics. However, their practical applications are limited. Strategies to overcome these limitations, such as optimizing the boron/hydrogen source and reducing agent, are summarized in this review. Ouyang developed a practical and low-cost method for regenerating MBH4 by ball milling, which has the potential to decrease the synthesis cost and increase the reversibility of metal borohydrides.

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.
