Abstract Lithium–Sulfur (Li─S) batteries are renowned for their high theoretical specific capacity and cost‐effectiveness. Nevertheless, performance could be impeded by obstacles including lithium dendrite growth polysulfide (LiPS) shuttle, particularly under harsh conditions. Herein, an economical strategy is reported modifying polyolefin separators (PP) with covalent organic polymer networks (TPE) to alter Li solvent structure, enhance lithium‐ion transport, suppress shuttle effects. Combining in situ/ex situ characterization calculations, it demonstrated that the lithiophilic groups (‐C═N‐) TPE@PP separator form strong interaction lithium, facilitating dissociation of Li─Solvent/LiPS‐solvent release freer ion shape a stable solid electrolyte interface rich LiF 3 N.

Abstract Magnesium metal batteries (MMBs), recognized as promising contenders for post‐lithium battery technologies, face challenges such uneven magnesium (Mg) plating and stripping behaviors, leading to uncontrollable dendrite growth irreversible structural damage. Herein, we have developed a Mg foil featuring prominently exposed (002) facets an architecture of nanosheet arrays (termed (002)‐Mg), created through one‐step acid etching method. Specifically, the prominent exposure facets, known their inherently low surface adsorption energies with atoms, not only facilitates smooth nucleation dense deposition but also significantly mitigates side reactions on anode. Moreover, evenly distribute electric field ion flux, enhancing transfer kinetics. As result, fabricated (002)‐Mg electrodes exhibit unprecedented long‐cycle performance, lasting over 6000 h (>8 months) at current density 3 mA cm −2 capacity mAh . Furthermore, corresponding pouch cells equipped various electrolytes cathodes demonstrate remarkable cycling stability, highlighting superior electrochemical compatibility electrode. This study provides new insights into advancement durable MMBs by modifying crystal structure morphology Mg.
