Abstract Modifying the current collector is a promising strategy to enable Li metal anodes with minimal consumption. Herein, scalable electrodeposition method introduced construct 3D ZnO/Zn(OH) 2 nanosheets on Cu foil (ZOH NSs–Cu foil). Cu(OH) nanowires are first formed via anodization, followed by electroconversion of 2+ and Zn ions.

The nanosheet structure provides large electrochemically active surface, reducing effective density. Furthermore, low charge transfer resistance promotes O/LiF‐rich solid electrolyte interphase (SEI) layer, further interfacial resistance. SEM analysis simulations confirm uniform deposition foil.

This binder‐free, approach offers precise control excellent electrochemical performance, advancing practical application anodes.

Abstract Lithium metal anodes suffer from uncontrollable volume expansion during electrochemical cycling due to the host‐free nature of lithium deposition, leading reduced Coulombic efficiency (CE) and shortened cycle life. In this work, a fluorine‐functionalized surface modification (FCMF) is applied carbonized melamine foam (CMF) using secondary chemical vapor deposition process, forming an amorphous nitrogen/fluorine co‐doped carbon layer ≈65 nm thick. The FCMF exhibits exceptionally low areal density 2.43 mg cm⁻ 2 , which only 28.5% that commercial 8 µm copper foil. Fluorine doping significantly enhances lithium‐ion affinity substrate, facilitating uniform throughout 3D framework. This results in ultrahigh average CE (99.78% for vs 99.44% CMF) substantially improves symmetric cell performance (2450 h 745 h). Additionally, LiFePO 4 (single‐side, 11.9 cm − ) | FCMF/Li full maintains over 400 cycles with 85.6% capacity retention at 2C. work introduces scalable method producing high‐performance current collectors batteries.

Abstract Electrolyte engineering plays a crucial role in the design of high energy‐density lithium‐sulfurized polyacrylonitrile (Li‐SPAN) batteries, promising energy storage technology. However, current predominant electrolyte systems face challenges anode dendrite growth and cathode polysulfide loss, which limit cycling stability Li‐SPAN batteries. Here, weakly solvating (WSE) primarily composed diethoxy methane (DEM) is proposed to simultaneously address at both electrodes. At anode, DEM's capability accelerates Li + diffusion desolvation, preventing out‐of‐plane deposition formation caused by concentration gradients surface. More significantly cathode, solvated exhibits stronger Lewis acidity, preferentially stabilizing S 3 2− intermediates via hard acid‐base interaction. These higher‐reduction‐state promote faster subsequent lithiation reactions, reducing loss while improving rate performance enhancements corresponding mechanisms are supported electrochemical spectroscopic characterizations. With this WSE, batteries achieve exceptional (0.087% capacity fade per cycle over 500 cycles 1 C), pouch cell life increases from 9 35 with 90.6% retention. This strategy provides valuable insights for developing high‐performance
