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.

The fundamental issues associated with Zn anodes prevent the commercialization of aqueous ion batteries. To address this, a simple dip‐coating method was used to coordinate thin layer branched polyethyleneimine (b‐PEI) polymer onto electrode surface. This process increases hydrophilicity and reduces interfacial resistance between electrolyte. Consequently, electrolyte leaching from hydrophilic coating is prevented, charge distribution uniform, stable electrochemical performance maintained over extended periods. In symmetric cell testing, b‐PEI@Zn anode exhibits lifespan 1400 h (3 mA cm −2 , 1 mAh ). Furthermore, full‐cell tests, demonstrates higher capacity (+26.05%) improved stability (95.4%) compared bare (0.5 A g −1 study presents practical surface modification strategy for underscores potential innovative polymer‐based coatings battery applications.
