Carboxyl‐Guided Ultrafine Zinc‐Acetate Templating Enables Closed‐Pore Engineering in Coal‐Derived Hard Carbon Anodes for High‐Performance Sodium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
In this study, ≈2 nm zinc acetate templates are uniformly anchored on the surface of NaOH‐etched bituminous coal via chelation between carboxyl groups and Zn2+. Subsequently, phenolic resin encapsulation is employed to construct a hard carbon material with abundant closed‐pore structures, achieving a reversible capacity of 370.9 mAh g−1 and an ICE of ...

Engineering Oxygen‐Terminated Hexagonal MBene for Accelerated Lithium Migration and Exceptional Lithium‐Ion Battery Performance

open access: yesAdvanced Science, EarlyView.
The synthesis of ultrathin Ti‐based 2D hexagonal transition metal borides (TiBTx h‐MBene) via ZnCl2 molten salt and the formed disorderly low‐boiling‐point Zn‐In intermediate, followed by TBAOH delamination. The delaminated structure, with O‐ and Cl‐terminations, improves Li‐ion transport, achieving 530 mAh g−1 at 0.1 A g−1 and 120 mAh g−1 at 10 A g−1,

Redox‐Active Halide Catholytes for Solid‐State Lithium Batteries

open access: yesAdvanced Science, EarlyView.
This review highlights emerging redox‐active halide catholytes that merge reversible transition‐metal redox chemistry with mixed ionic–electronic conductivity. Integrating these materials into composite cathodes of all‐solid‐state batteries boosts reversible capacity by 20–50% and reduces electronic transport tortuosity.

Activation of Cascade Pathway for Oxygen Reduction via 4f‐3d Orbital Ladder‐Driven Dual‐Site Synergy

open access: yesAdvanced Science, EarlyView.
The designed Fe3N/CeO2 heterostructure constructs a unique 4f‐3d orbital ladder through Ce─O─Fe coordination, enabling dual orbital coupling and activating both phases. The resulting dual‐site synergistic effect at the heterointerface triggers a cascade mechanism that simultaneously breaks conventional scaling relationships in the ORR and facilitates ...

Iron Nanoparticles on Porous Carbon Discs: Electrocatalysts with Over 30% Energy Efficiencies for the Production of Ammonia from Nitrate

open access: yesAdvanced Science, EarlyView.
Iron nanoparticles on carbon disc matrixes (CD@Fe) are engineered, showing a high surface area of 424 m2 g−1 and micro/mesoporosity. The CD@Fe showed promising electrocatalytic performance for the nitrate reduction to ammonia with ammonia yield rates of 1.8–13.5 mg h−1 cm−2 at overpotentials of −0.2–−0.6 V (vs.
