Abstract A large concentration gradient originating from sluggish ion transport on the surface of Zn metal anodes will result in uneven 2+ flux, giving rise to severe dendrite growth, especially at high current density. Herein, an acceleration layer is introduced by a facile separator engineering strategy realize modulated flux and dendrite‐free deposition. Zinc hexacyanoferrate as modifying agent featuring strong zincophilicity rapid diffusion tunnel can enable fast trap for near electrode immediate onto deposition sites, respectively. The effect substantiated improved conductivity, decreased activated energy, promoted transference number, which moderate guide homogenous distribution. As result, guarantees Zn||Zn symmetrical cells with long‐term stability 2700 h 2 mA cm −2 , 1770 density 10 . Moreover, cycling rate capability full different cathodes be substantially modified separator, validating its superior practical feasibility. This study supplies new scalable approach tailoring robust

Developing ionotronic interface layers for zinc anodes with superior mechanical integrity is one of the efficient strategies to suppress growth dendrites in favor cycling stability aqueous zinc-ion batteries (AZIBs). Herein, we assembled robust 2D MXene-based hydrogel films cross-linked by 1D cellulose nanofibril (CNF) dual networks, acting as stabilize Zn anodes. The MXene-CNF integrated multifunctionalities, including a high in-plane toughness 18.39 MJ m-3, in-plane/out-of-plane elastic modulus 0.85 and 3.65 GPa, mixed electronic/ionic (ionotronic) conductivity 1.53 S cm-1 0.52 mS cm-1, zincophilicity binding energy (1.33 eV) low migration barrier (0.24 Zn2+. These endowed coupled multifield effects, strong stress confinement uniform ionic/electronic field distributions on anodes, effectively suppressed dendrite growth, proven experiments simulations. An example MXene-CNF|Zn showed reduced nucleation overpotential 19 mV, an extended life over 2700 h Zn||Zn cells, capacity 323 mAh g-1 Zn||MnO2 compared bare Zn. This work offers approach exploring mechanically 1D/2D AZIBs.
