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.

Abstract Commercial 3D zinc foam anodes with high deposition space and ion permeation have shown great potential in aqueous batteries. However, the local accumulated stress from its high‐curvature surface exacerbates Zn dendrite issue, leading to poor reversibility. Herein, we employed zincophilic N‐doped carbon @ Sn composites (N‐C@Sn) as nano‐fillings effectively release of curvature foams toward dendrite‐free anode battery (AZIB). These electronegative conductive N‐C@Sn supporters can provide a highly channel for initial nucleation reduce current density regulating deposition. Uniform further assists homogenous distribution on platting surface, which gives positive feedback loop improve As result, composite (ZCSn Foam) symmetric cell achieves long cycle lifespan 1100h at 0.5 mA cm −2 , much more than that Foam (∼80 h lifespan). The full ZCSn Foam||MnO 2 exhibits remarkable reversibility 67% retention after 1000 cycles 0.8 A g −1 76% 1600 Ag . This 3D‐constructing strategy may offer promising practical pathway metal application.

Abstract Uncontrolled dendrite growth, hydrogen evolution and corrosion challenges associated with zinc (Zn) anodes significantly restrict the practical application of batteries. Herein, a liquid metal gallium (Ga) interface is in situ formed on carbon paper (CP) by electrochemical co‐deposition to construct dendrite‐free Zn‐Ga@CP composite electrode which can regulate transport chemistry Zn deposition at electrode/electrolyte interface. Notably, concurrent reduction 2+ Ga 3+ results formation self‐supporting 3D interpenetrating structure Ga. Compared foil electrodes, highly conductive layer lowers nucleation energy barrier promotes homogeneity electric field ion flux, induces uniform Zn. In addition, low chemical activity prevents high rate reaction parasitic reactions. As result, symmetric cell delivers stable cycling >350 h discharge depth 23.3% ultra‐low voltage hysteresis. Moreover, coin‐type pouch‐type full cells exhibit excellent durability good mechanical stability. This work provides novel regulation strategy for achieving high‐performance anode
