Summary: Anode-free lithium metal batteries (AFLMBs) are considered as potential high-energy devices in the future. To overcome the challenges of interface reactions and internal short circuits, a solvent-free approach is proposed to fabricate deformable sulfide composite solid electrolyte (SCSE-4) by incorporating lithium argyrodite (LPSC) and other materials. The SCSE-4 electrolyte exhibits high Li-dendrite inhibition capability and delivers ultra-stable cycling with high coulombic efficiency.

Summary: Designing inorganic solid electrolytes with excellent electrochemical stability and high ionic conductivity is crucial for all-solid-state batteries. However, the electronic conduction of decomposition products causes an imbalance between ionic transport and electrochemical stability window in these electrolytes. In this study, a computational approach that combines energy analysis and dynamically determined decomposition pathway is proposed to depict the competing relationship between ionic transport and stable electrochemical window in solid electrolytes. Furthermore, the high ionic conductivity and wide electrochemical stability window of Li-Si-B-S solid electrolytes are explained using this approach, which features shared corner and edge from tetrahedral SiS4/BS4.

Summary: Lithium-ion batteries (LIBs) are widely used due to their high energy density, low cost, and long cycle life. However, safety issues in traditional liquid batteries have led researchers to explore the use of rigid solid-state electrolytes (SSEs) instead. Among the SSEs, sulfide SSEs, particularly argyrodite SSEs, have garnered attention for their high ionic conductivity and thermal stability. Interfacial problems between argyrodite SSEs and the anode, including interfacial reactions and lithium dendrites, are considered important factors affecting their availability. This mini review provides an overview of the behavior, properties, and interface problems of argyrodite SSEs and discusses strategies to solve these problems and stabilize interfaces. The paper concludes with a brief outlook on argyrodite SSEs.

Summary: Low electrolyte/sulfur ratio is an important factor in increasing the energy density of lithium-sulfur batteries. By using catalytic hosts to suppress the shuttle effect, the E/S has been widely lowered. However, the shelf-life of these cathodes has not been studied. Our research reveals that the adsorption strength of commonly-used catalytic hosts is critical for effectively hindering the disproportionation of polysulfides.

Summary: Domain boundaries are important active sites for electrochemical energy storage materials. Layered double hydroxides tend to grow into single crystalline nano sheets, but efforts have been made to design hierarchical structures to provide more exposed electroactive sites. In this study, low angle grain boundaries were introduced into flakes of Ni/Co layered double hydroxides, resulting in defect-rich nano flakes that self-assembled into hydrangea-like spheres. These spheres further constructed a hollow cage structure. The formation of hierarchical structure and grain boundaries was explained by the synergistic effect of the Ni2+/Co2+ ratio. The battery-type electrode material fabricated from the NiCo-LDH-2 showed significantly enhanced specific capacitance and energy density.

Summary: We report a novel nitrogen-doped bulk oxide (YTaO4-xNy) with good visible light response. Through density functional theory calculations, the band gap of YTaO4 precursor was narrowed to 2.4 eV on YTaO4-xNy, and the valence band maximum was uplifted. When used as the H2-evolving photocatalyst in a Z-scheme overall water splitting system with PtOx/WO3 as the oxygen evolution photocatalyst, Pt/YTaO4-xNy showed promising performance. This study enriches the material database of nitrogen-doped oxide and demonstrates its potential application in solar-to-chemical conversion.
