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 Developing a robust zinc (Zn) anode, free from Zn dendrites and unwanted side reactions, relies on designing durable efficient interfacial protection layer. In this study, gradient coating technology is employed to construct hierarchically structured composite of Sn with diamond‐like carbon (DLC/Sn‐DLC) as an artificial protective The DLC framework endows DLC/Sn‐DLC layer high stability adaptability, achieving long‐term the anode–electrolyte interface. gradual‐composite Sn, its Sn─O─C interface chemical bonds, facilitates rapid charge transfer offers ample zincophilic sites at base, promoting uniform 2+ reduction reaction deposition. Additionally, exhibits “lotus effect” favorable hydrophobic properties, preventing water‐reduced reactions.

Abstract The practical application of aqueous rechargeable batteries faces several challenges due to the limited stability window electrolytes and parasitic side reactions, such as corrosion, passivation, gas evolution, co‐intercalations. solid electrolyte interphase (SEI) formed at electrode/electrolyte interface plays a critical role in determining interfacial properties battery performance. Efforts are being made develop effective SEIs, functionalize layers, explore various hybrid that facilitate SEI formation. This review highlights interphasial structures batteries. First, common issues encountered by specific characteristics lithium‐ion, sodium‐ion, zinc‐ion, aluminum‐ion outlined. Then tactics used improve cycle introduced compared working principles key parameters from context modification discussed. Finally, constructive insights suggestions for developing high‐performance offered, with focus on formation layer design.

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.

Zinc dendrite, active iodine dissolution, and polyiodide shuttle caused by the strong interaction between liquid electrolyte solid electrode are chief culprits for capacity attenuation of aqueous zinc-iodine batteries (ZIBs). Herein, mullite is adopted as raw material to prepare Zn-based solid-state (Zn-ML) ZIBs through zinc ion exchange strategy. Owing merits low electronic conductivity, diffusion energy barrier, adsorption capability, Zn-ML can effectively isolate redox reactions anode AC@I
