Sulfonated Cellulose Acetate Nanofibers Induced Zincophilic‐Hydrophobic Interface to Regulate Ion Transport for Long‐Lifespan Zinc‐Iodine Batteries

Advanced Science, EarlyView.
Sulfonated cellulose acetate (SCA) nanofiber membrane with zincophilic‐hydrophobic property is constructed on the surface of the Zn anode by the electrospinning technique to tune the 3D deposition behavior of Zn2+ by chemisorption and micro‐sized physical structure. The negatively‐charged groups of SCA nanofiber membrane form an electrostatic repulsion

Enhancing Interfacial Dioxygen Bridging Dynamics of Waste‐Derived Cathode Catalysts for Augmented High‐Rate Performance in Li‐O2 Batteries

Advanced Science, EarlyView.
This study fabricates Fine Slag/Ti4O7@TiC hybrids with interfacial dioxygen bridge coupling to optimize oxygen redox dynamics in lithium‐oxygen batteries (LOBs). Lattice distortion from oxygen vacancies and inherent charge repulsion of Ti‐O‐C interfacial coupling reconstruct and refine the surface coordination environment.

Regulating Zinc Anode Interface with an Environmental Biomass‐Derived Additive for Long‐Lifespan Aqueous Batteries

Advanced Science, EarlyView.
A biomass‐derived additive synthesized from chitin, 3‐acetylamino‐5‐acetylfuran (3A5AF), resolves key stability issues such as uncontrolled dendrite growth, hydrogen evolution reaction, and corrosion of zinc anodes by reconstructing the solvation structure of the electrolyte and protecting the anode interface. ABSTRACT Aqueous zinc‐based batteries face

Unveiling Copper‐Induced Phase Transitions and Degradation Mechanisms of Transition Metal Sulfide Anodes for Sodium‐Ion Batteries

Advanced Science, EarlyView.
Sodium polysulfides, which are generated from TMS anodes, react with the Cu current collector, thereby triggering Na‐Cu–S interfacial phase formation. Simultaneously, transition metals undergo ionization and redeposition on the counter electrode. The coupled processes drive the phase evolution of TMS toward the stable Cu1.8S phase.

Unraveling Hydride‐Driven Multiphasic Reduction Toward Tunable Germanium Structures for Lithium‐Ion Batteries

Advanced Science, EarlyView.
The sodium hydride (NaH)‐mediated reduction of germanium dioxide yields distinct Ge structures depending on the amount of reductant, revealing the dual roles of NaH in the reduction pathways. The synthesized Ge under off‐stoichiometric conditions exhibits a porous morphology and reduced crystallinity, which effectively mitigates volume expansion during

All‐Inorganic Cesium Zinc Halides as Ultra‐Stable Lead‐Free Perovskite Electrodes for Li‐Ion Batteries

Advanced Electronic Materials, EarlyView.
Here we explore the use of lead‐free metal halide perovskites in lithium ion batteries. Cesium zinc chloride and bromide both show reasonable discharge capacities and high stability compared to lead based perovskites. ABSTRACT Halide perovskites have recently gained attention for use as electrode materials in lithium‐ion batteries. However, lead halide
