Summary: Ion insertions involving electrode-electrolyte interface process has been a challenge, but this study reveals a mechanism for fast energy storage by deprotonation of NH4+ and dissociation of H2O molecules at the interface, providing sufficient H3O+ for ion insertion into material structures. In situ attenuated total reflection-Fourier transform infrared ray method and density functional theory calculations confirm the thermodynamic adsorption and deprotonation of NH4+ on the surface of monoclinic VO2 to provide H3O+. As a result, high specific capacity (>300 mAh g(-1)) and fast ionic insertion/extraction (<20 s) can be achieved in VO2(B) anode. This interface derivation proposes a new path for designing proton ion insertion/extraction in mild electrolyte.

Summary: VO2(B) is a leading candidate cathode material for AZIBs, but the primary challenges of slow kinetics and limited actual capacity have not been resolved yet. In this study, the effects of ion doping on VO2(B) were investigated, and it was found that heteroatom (Cr, Mo, and W)-doped VO2(B) cathode can verify the theoretical calculation results. Among them, Mo-doped VO2(B) showed the best electrochemical performance, with excellent initial specific capacity (264.6 mA h g(-1)) and retention rate (81.4 %) at 3.0 A g(-1). It also exhibited a faster Zn2+ ion diffusion coefficient (2.1x10(-8) vs 2.6x10(-9) cm(2) S-1) compared to pure VO2(B). Furthermore, it achieved a promising energy density of 207.3 Wh kg(-1) at 0.1 A g(-1) and a power density of 3094.5 W kg(-1) at 5.0 A g(-1). This finding provides insights into the modification mechanism of heteroatom-doped materials and can guide electrode design for improved performance.

Summary: Highly fluorinated electrolytes can improve the solvation sheath of Li+ and achieve high-quality solid-electrolyte interphases (SEIs) for stable cycling of Li metal batteries (LMBs). In this study, the effect of fluorinated engineering-based electrolytes on Li+ solvation structure and electrochemical performance was investigated. The all-fluorinated electrolyte containing fluoroethylene carbonate (FEC) and ethyl (2,2,2-trifluoroethyl) carbonate (ETFEC) was found to optimize the Li+ solvation environments, resulting in stable LiF-rich interface and inhibition of Li dendrites. Consequently, Li||Cu cells achieved high Coulombic efficiency (CE) of 98.3% at 0.5 mA cm-2 and superior cycling stability.

Summary: This study investigates the catalytic mechanisms and adsorption properties of main-group single-atom catalysts (MSACs) through first-principles calculations. The results show that as the single-atom in MSACs moves down the periodic table, their adsorption capabilities become even more enhanced. MSACs derived from the fifth and sixth periods exhibit mild adsorption capabilities and robust catalytic activity. Additionally, a linear correlation is identified between the adsorption energy, p-band center, and electronegativity of the main-group atom in MSACs, which serves as an effective descriptor for oxygen reduction reaction (ORR) activity. The study also reveals two distinct interaction patterns of MSACs with oxygenated species and highlights the role of carbon support species in enhancing the adsorption abilities of MSACs.

Summary: Ionhydration plays a crucial role in various fields, but the nature of ion hydration at the molecular level remains inconsistently understood. This study combines neutron scattering, wide-angle X-ray scattering, and molecular dynamics to systematically quantify the hydration ability of alkali metal and halide ions based on static and dynamic hydration numbers. The static hydration number is determined from positional information, while the dynamic hydration number measures the average number of water molecules in the first coordination shell of an ion over a residence time. These hydration numbers provide valuable insights for understanding different natural phenomena.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
