Fabrication and Lithium Storage Performance of Trigonal W2N Thin-Film Anode

Abstract The preparation, characterization of materials, and electrochemical performance of trigonal W2N thin film as the anode material for lithium-ion batteries have been reported. The trigonal W2N thin film with the space group of P3̅ was synthesized by the sputtering depositi...

Precursor‐Level Molecular Coupling Enables High‐Fill‐Factor Wide‐Bandgap Perovskite Solar Cells and 29.63% All‐Perovskite Tandems

ABSTRACT Wide‐bandgap (WBG) perovskites with a ∼1.78 eV bandgap are essential for monolithic all‐perovskite tandem cells, yet their efficiency and stability are limited by complex precursor chemistry, uncontrolled crystallization, defect formation, and photoinduced halide segrega...

A Focused Review on Zinc‐Anode Protection for Durable Aqueous Zinc–Iodine Soft‐Gel Electrode Batteries

ABSTRACT Aqueous zinc–iodine batteries offer a safe and low‐cost storage option, but their durability is limited by coupled zinc‐anode degradation and iodine‐species crossover. Soft‐gel iodine cathodes can improve iodine retention through confinement and molecular interactions, y...

Mg-Ce-Mn Alloy Negative Electrode for Rechargeable Magnesium Batteries

Abstract The commercialization of rechargeable magnesium batteries is hindered by nonuniform Mg stripping/plating and severe side reactions of Mg negative electrode. Herein, a ternary Mg-Ce-Mn alloy with trace solid-solution elements is proposed as negative electrode. The refined...

Electric/Thermal Coupling Field Promotes Phonon Delocalization to Accelerate Defect‐Repair Kinetics in Spent LiFePO 4

ABSTRACT Solid‐phase regeneration is widely considered as the most promising scalable approach for recycling spent LiFePO 4 (S‐LFP) cathode. However, the sluggish defect‐repair kinetics in traditional solid‐phase routes remains mechanistically unclear, limiting the practical depl...

Dynamic Match Regulation Strategy for Dendrite‐Free Zn Anode

ABSTRACT The undesirable Zn‐dendrite growth seriously impedes the development of aqueous zinc metal batteries. Compared to thermodynamic improvements reported in most strategies, kinetic manipulation is neglected, limiting the deep research on metal plating process and narrowing...

Coupled Photon Transport and Interfacial Charge Utilization in ACT/g‐PAN for Photocatalytic CO 2 Reduction

ABSTRACT Integrating microscopic catalyst design with macroscopic photophysical reaction engineering is important for improving solar‐driven CO 2 reduction. However, previous studies have largely focused on the molecular‐level optimization of catalysts, whereas the coupled effect...

In Situ Sodiation of CoSe 2 Modulating Charge Transfer in Sodium−Selenium Batteries

ABSTRACT Selenized polyacrylonitrile (SePAN), characterized by the unique C−Se covalent bonds, can suppress the formation of polyselenides and their associated shuttle effect in sodium−selenium (Na−Se) batteries. However, its polymeric structure and distinct conversion mechanism...
