Abstract The practical realization of aqueous zinc‐ion batteries relies crucially on effective interphases governing Zn electrodeposition chemistry. In this study, an innovative solution by introducing ultrathin (≈2 µm) biomass membrane as intimate artificial interface, functioning nature's ion‐regulation skin to protect zinc metal anodes is proposed. Capitalizing the inherent properties natural reed membrane, including multiscale ion transport tunnels, abundant ─OH groups, and remarkable mechanical integrity, demonstrates efficacy in regulating uniform rapid 2+ transport, promoting desolvation, (002) plane electrodeposition. Importantly, a unique situ electrochemical Zn─O bond formation mechanism between electrode upon cycling elucidated, resulting robustly adhered interface covering anode surface, ultimately ensuring dendrite‐free highly reversible anodes. Consequently, approach achieves prolonged cycle life for over 1450 h at 3 mA cm −2 /1.5 mAh symmetric Zn//Zn cells. Moreover, exceptional cyclic performance (88.95%, 4000 cycles) obtained active carbon‐based cells with mass loading 5.8 mg . offers cost‐effective environmentally friendly strategy achieving stable batteries.

Abstract Zn foil pretreatment is a direct route to alleviating anode instability and maintaining high energy performance in metal batteries. Unfortunately, prevailing methods for achieving an ideal surface texture do not enable durable operation under large depth of discharge, thus impairing the utilization ratio. etching more feasible way control texture, but this approach remains relatively unexplored. In study, general strategy reported engraving aprotic media realize efficient terms stability. These tests are performed using high‐valence ions (especially Mo 5+ ) environment as key etchant render homogenously‐distributed, 3D porous architecture on surface. Comprehensive experimental results theoretical simulations revealed enhanced nucleation growth. This specially designed electrode exhibited long lifespan with discharge 88% symmetric cells.

Abstract Due to its abundance of natural resources, high theoretical capacity, and suitable redox potential (−0.76 V vs SHE), Zn anode has received extensive attention both from academy industry. However, the coexistence H 2 O, which is unfortunately thermodynamically unstable, always involves severe metal corrosion, evolution, dendrite growth, resulting in low reversibility anode. Herein, a phase transfer method adapted design porous conductive protective layer on anode, denoted as (PVDF (Polyvinylidene fluoride)/CNTs(Carbon Nanotubes)‐PT(phase transfer) @ Zn). Based situ characterization, COMSOL simulation, migration energy barrier calculation, it can be demonstrated that PVDF/CNTs‐PT effectively inhibited production dendrites side reactions triggered by achieving uniform deposition. Especially, full picture deposition observed using computed tomography (CT). The symmetrical cell demonstrates dendrite‐free plating/stripping possesses much better cycle stability than bare Zn. A stable rechargeable battery demoed through coupling with commercial O 5 . strategy showcases feasible pathway inhibit aqueous ion battery, opening promising avenue for construction protection layer.
