Summary: In this study, the properties of KTiOPO4Mx (M = K, Na, and Li; x = 0.000-1.000) as an anode for PIBs, SIBs, and LIBs were investigated using density functional theory calculations and ab initio molecular dynamics simulations. The results reveal that KTiOPO4 shows superior electrochemical performance as an anode for PIBs compared to SIBs and LIBs, in terms of average voltage and ion diffusion kinetics. Furthermore, the KTiOPO4 anode exhibits high structural stability, and alkali ion intercalation contributes to accelerating ion diffusion during the charging process.

Summary: The role of anions in antiperovskites was investigated through theoretical and experimental studies, revealing that replacing polarizable H- anions with ionic F- anions in the M(3)FCh family does not slow down ion diffusion. It was found that the low-frequency rotational modes of the octahedron in cubic M(3)FCh facilitate fast ionic diffusion, showing a correlation between tolerance factor and ionic transport. The cubic iodine-doped Li3FSe exhibited a room-temperature ionic conductivity of 5 x 10(-5) S/cm with a bulk activation energy of 0.18 eV.

Summary: The luminescence properties of YVO4:Dy3+ were modified by co-doping alkali metals (M = Li, Na, and K). Co-doped materials were prepared by hydrothermal technique followed by calcination. The properties of crystal phase and photoluminescence were affected by the co-doping of alkali metals. The most intense emission peak was observed at 573 nm, and K+ effectively enhanced its intensity. The optimum concentration of K+ co-doping was found to be 10 at.%. The calculated band gaps and CIE chromaticity color coordinates indicate the potential application of YVO4:Dy3+ in display devices.

Summary: Development of advanced high-voltage electrolytes is crucial for high-energy-density lithium metal batteries. Weakly solvating electrolytes can produce unique anion-driven interphasial chemistry by altering the solvent's solvating power. A new-type weakly solvating electrolyte regulated by the anion was successfully used to achieve stable cycling of dimethoxyethane at 4.6 V. The electrolyte's solvation structure and the degree of dissociation of salts were found to affect the electrochemical performance of the lithium metal batteries.

Summary: The crystal structure and hydrogen storage properties of a new equiatomic TiZrNbCrFeNi high-entropy alloy (HEA) were investigated. The alloy exhibited an AB-type configuration, selected through thermodynamic calculations and showed the ability to absorb 1.5 wt% of hydrogen at room temperature without activation. Cyclical testing revealed changes in the fractions of two C14 Laves phases, with one phase having higher reactivity towards hydrogen. The alloy exhibited a single C14 Laves phase after dehydrogenation at 473 K, and microstructural analysis showed excellent homogeneity and element distribution.

Summary: Magnesium and its alloys are extensively studied for solid-state hydrogen storage, but there are challenges in the kinetics and thermodynamics of hydrogenation and dehydrogenation. Severe plastic deformation methods have been utilized to improve the activation, air resistance, and kinetics of Mg-based hydrogen storage materials by introducing ultrafine/nanoscale grains and crystal lattice defects. These deformed materials, particularly with alloying additives or second-phase nanoparticles, exhibit fast hydrogen absorption/desorption kinetics and good cycling stability. The study also highlights the application of severe plastic deformation methods in hydrogen binding-energy engineering and the synthesis of new magnesium alloys for reversible low/room-temperature hydrogen storage.

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: 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.
