Abstract The rampant dendrites growth caused by uncontrolled deposition of Zn 2+ ions at metal anode poses a significant obstacle to the practical applications aqueous zinc‐ion batteries (ZIBs). Herein, an ultrathin (5 µm) aramid nanofiber (ANF) separator is reported enhance stability and ZIB energy density. Through systematic experimental studies DFT simulations, it demonstrated that ANF with unique surface polarity can modify solvation configuration, facilitate desolvation, regulate orientation ions. Consequently, demonstrates 85‐fold increase in running time beyond 850 h compared conventional glass fiber 5 mA cm −2 /2.5 mAh . Even under harsh depth discharge conditions 50% 80%, anodes still sustain extended cycling periods over 475 200 h, respectively. As pairing this thin high‐areal‐capacity Mn 2.5 V 10 O 24 ∙5.9H 2 cathode low negative capacity/positive capacity ratio (2.64) full cell, superior gravimetric/volumetric density (129.2 Wh kg −1 /142.5 L ) achieved, far surpassing majority counterparts literature. This work offers promising for promoting utilization energy‐dense ZIBs.

Aqueous zinc-ion batteries (AZIBs) exhibit promising prospects in becoming large-scale energy storage systems due to environmental friendliness, high security, and low cost. However, the growth of Zn dendrites side reactions remain heady obstacles for practical application AZIBs. To solve these challenges, a functionalized Janus separator is successfully constructed by coating halloysite nanotubes (HNTs) on glass fiber (GF). Impressively, different electronegativity inner outer surfaces HNTs endows HNT-GF with ion-sieving property, leading significantly transference number
