Abstract The advancement of K metal anodes has long been hindered by challenges including dendrite proliferation and volume expansion amid electrochemical cycles. Generic interlayer design for extended its uptake/release mechanism remain unexplored to date. Herein, a generic alloy‐boosted strategy is reported devise ZnX‐loaded (X = S, Se or Te) porous carbon nanofiber (PCNF) membrane as an efficient 3D interphase layer anodes. Theoretical computations experimental investigations suggest that representative ZnTe acts alloying site, thereby reducing the nucleation energy barrier optimizing deposition pattern K. Such maneuver enables dendrite‐free plating within interface layer, which facilitates construction anode. As result, symmetric cell modified with ZnTe@PCNF demonstrates lifespan over 3100 h. When coupled cathode, full delivers capacity retention 94% after 500 cycles at 1.0 A g⁻¹, showing potential development practically viable batteries.

Abstract Hybrid Li‐ion/metal batteries can optimize energy density and lifespan. However, hybrid face key obstacles like poor Li reversibility dendrite growth. Herein, carbon nanofibers encapsulated by graphitized layers decorated with uniformly distributed Ag nanoparticles (G‐CF‐Ag) are designed, interfacial chemistry is regulated to enhance the performance of batteries. The C sp2 structure in effectively reduces side reactions electrolytes, improve lithiophilicity induce uniform plating/stripping. A weakly solvated electrolyte 1 m LiFSI‐THF‐0.5wt.%LiNO 3 induces achieve rapid transport Li‐ions under fast charging conditions low temperatures. Consequently, a high‐capacity deposition 500 mA h g −1 (≈1.25 cm −2 ), G‐CF‐Ag||Li delivers an ultra‐high plateau capacity 716 at voltages below 0.1V 0.2 C, maintains average CE 99.1% over 150 cycles 2 charging. Notably, cell continues operate stably even wide temperature range from 50°C ‐20°C. Furthermore, ultra‐low N/P ratio 0.3, G‐CF‐Ag||NCM811 provides high 587.5 W kg C. At same ratio, G‐CF‐Ag||LFP stable cycling

Abstract Zinc‐based batteries are emerging as promising alternatives to mainstream technologies due their superior safety, cost‐effectiveness, and abundance of raw materials. However, zinc anodes, exhibit insufficient cycle life low utilization in aqueous electrolytes, mainly owing shape change passivation. While nanostructuring Zn anodes has been explored for Zn‐Ni rechargeable alkaline batteries, no explicit electrochemical studies have elucidated how nanostructures, fabricated the oxidized state, reduced during initial formation step, yielding elemental Zn. In this work, a hydrothermal synthesis freestanding electrodes is proposed, based on vertically aligned ZnO nanorods grown directly carbon cloth (CC) ( ZnO/CC ). mitigates passivation, while fiber network confines soluble Zn(II) intermediates, hindering diffusion into electrolyte bulk. Moreover, CC substrate provides optimal electronic contact active material, acts built‐in current collector. This work investigates evolution first reduction cycle, with emphasis morphochemical nanostructure changes rather than establishing benchmark anode. Electrochemical measurements combined advanced characterization techniques, high‐resolution transmission electron microscopy (HRTEM), X‐ray absorption hyperspectral imaging via scanning (STXM) ptychography at L‐edge. multimodal approach offers unprecedented insights ZnO‐to‐Zn guide future Zn‐ion anode design.

Fast charging of lithium-ion batteries (LIBs) is now a critical challenge for the development electric vehicles (EVs). The difficulty achieving fast-charging LIBs arises from sluggish Li-ion transport in both electrolytes and electrode materials charge transfer processes across electrode–electrolyte interphases (EEIs). To overcome these obstacles, it important to fully understand mechanism Li+ materials, electrolytes, EEIs. Spectroscopic techniques are useful tools detect structural changes reveal mass during cycling batteries, which helpful guide design novel as well optimal batteries. In this paper, recent advancements application spectroscopic reviewed. We focus on key roles revealing reasons improved capabilities LIBs, including their fields electrolyte engineering, interphase modification, Li-plating detection, composition/structure optimization. Moreover, electrospectroscopic exploring interfacial reactions electrodes also discussed. Finally, some perspectives research directions improving advance provided.
