ABSTRACT Aqueous polysulfide‐based redox flow batteries are promising for large‐scale energy storage, yet their practical application is severely hindered by sluggish polysulfide conversion kinetics and the accumulation of intermediate species. Herein, we propose an orbital‐regulated stepwise catalytic strategy based on d‐electron complementarity and construct a NiS/MnS heteros…

ABSTRACT Solid electrolytes (SE) such as Li _6.5 La ₃ Zr _1.5 Ta _0.5 O ₁₂ (LLZTO) have the potential to enable the production of safe, high‐capacity lithium (Li) metal batteries, but remain vulnerable to Li filaments. Applying in‐plane residual compressive stress to suppress these dendrites provides a possible solution. Herein, we quantify the effectiveness of comp…

ABSTRACT High‐voltage lithium‐metal batteries are pivotal for increasing energy density but suffer from aluminum (Al) current collector corrosion. While the native Al ₂ O ₃ layer provides thermodynamic stability, corrosion persists through electric‐field‐driven Al ³⁺ migration. Guided by P. Marcus theory, we identify that the total potential drop across the Al/Al ₂ …

ABSTRACT Solid oxide electrolysis cells (SOECs) hold significant potential for efficient, high‑rate conversion of CO ₂ and H ₂ O into syngas driven by renewable electricity. However, SOEC performance is often constrained by the scarcity of fuel electrode materials that combine high activity with structural stability for CO ₂ and H ₂ O electrochemical reduction. Here…

ABSTRACT Porous‐carbon‐based hard carbons have attracted widespread attention as anodes for sodium‐ion batteries owing to the high plateau capacity; however, their practical application is constrained by an intrinsic trade‐off: constructing abundant closed pores enhances capacity but impedes charge transport and compromises structural stability. Herein, we introduce a solvent‐m…

ABSTRACT Solid polymer electrolytes are promising for high‐energy‐density alkali metal batteries but are hindered by excessive thickness, insufficient interfacial contact, and uncontrolled dendrite growth. Herein, we introduce a scalable in situ polymerization strategy to fabricate ultrathin (∼10 µm) yet robust solid‐like polymer electrolytes (SPE‐Na and SPE‐Li) that simultaneo…

ABSTRACT RuO ₂ is a promising anode catalyst for PEMWE but suffers rapid degradation at ampere‐level current densities. Previous studies have linked the instability of ruthenium‐based catalysts to excessive Ru─O covalency, yet the mechanism governing this covalency remains unclear. Here, we introduce isovalent metals (M: Ti ⁴⁺ /Hf ⁴⁺ ) to modulate the Ru─O bond strengt…

ABSTRACT This study presents a novel electrochemical hydrogenation (EH‐DPM) system that integrates clean hydrogen production and storage by utilizing a diphenylmethane (H0‐DPM, DPM) /dicyclohexylmethane (H12‐DPM, DCM) pair as a liquid organic hydrogen carrier (LOHC). The system operates in a full‐cell configuration, coupling a cathode for the electrochemical hydrogenation of H0…

ABSTRACT The structural and compositional heterogeneity at electrolyte/electrode interfaces critically determines the functionality, performance, and stability of modern Li‐ion batteries. However, atomic‐scale characterization remains challenging due to the high degree of disorder, spatial confinement, and dynamic evolution of these interfaces, leaving their role in Li‐ion tran…

ABSTRACT When CO ₂ undergoes a two‐electron partial reduction during the discharging process of Li‐CO ₂ batteries, it produces thermodynamically active Li ₂ C ₂ O ₄ , which readily decomposes during subsequent charging. This offers a promising opportunity to mitigate the large charging overpotential and enhance the battery's cycling stability. However, as an inte…
