Abstract Aggressive side reactions and dendrite growth, associated with the unstable Zn anode/electrolyte interface, have impeded practical application of metal‐based batteries. Here, a donor‐acceptor (D‐A) polymer is employed to reconstruct robust supramolecular (SP) protective layer achieve highly stable anodes. The D‐A possessing abundant electron donor acceptor sites can dynamically co‐crosslink water molecules 2 ⁺ through multivalent dipole interactions (MDIs), resulting in formation network. MDIs disrupt original strong hydrogen‐bonding network within polymer, leading reconfiguration chain conformations an increase intermolecular free volume exposing more widely distributed dipoles, thereby regulating 2+ desolvation behavior facilitating rapid uniform plating. Meanwhile, resultant endows SP ultra‐high mechanical modulus 10.4 GPa, which homogenize stress distribution during plating process for effective suppression. Consequently, SP‐assisted asymmetric cell achieves nearly 99.94% Coulombic efficiency over 9000 cycles, enabling Zn/Zn cycle 540 h under ultrahigh 92% utilization. Outstanding cycling stability also successfully demonstrated high mass‐loading (≈12.8 mg cm −2 ) pouch cells, further demonstrating its prospects applications.

Zinc ion batteries (ZIBs) have emerged as promising candidates for renewable energy storage owing to their affordability, safety, and sustainability. However, issues with Zn metal anodes, such dendrite growth, hydrogen evolution reaction (HER), corrosion, significantly hinder the practical application of ZIBs. To address these issues, organic solid electrolyte interface (SEI) layers gained traction in ZIB community they can, instance, help achieve uniform plating/stripping suppress side reactions. This article summarizes recent advances artificial SEI including fabrication methods, electrochemical performance, degradation suppression mechanisms.

Ternary nickel-rich layered oxide LiNi0.8Co0.1Mn0.1O2 (NCM811) is recognized as a cathode material with promising future, attributed to its high energy density. However, the pulverization of particles, structural collapse, and electrolyte decomposition are closely associated fragile cathode-electrolyte interphases (CEI), which seriously affect electrochemical performances ternary high-nickel materials. In this paper, fluorine- nitrogen-containing methyl-2-nitro-4-(trifluoromethyl)benzoate (MNTB) was selected, synergistically regulated fluoroethylene carbonate (FEC) generate robust CEI film. The preferential MNTB/FEC results in formation an inorganic-rich (Li3N, LiF, Li2O) film uniformly dense stable characteristics, conducive migration Li+ stability NCM811 structure enhances cycling battery system. Simultaneously, MNTB effectively suppresses adverse reaction increased polarization caused by higher interface impedance due conventional single FEC additives, further improving rate capability battery. Moreover, can eliminate HF, preventing corrosion on cathode. Under synergistic effect MNTB/FEC, after 300 discharge cycles at cutoff voltage 4.3 V current density 1 C (2 mA cm-2), capacity NCM811||Li 150.12 h g-1 retention 81.10%, while it only 32.8% for standard (STD). discharged MNTB/FEC-containing about 115.43 7 C, considerably than that STD (93.34 g-1). study, designed novel solvent will contribute enhanced materials voltages same time provide effective modified strategy enhance commercial electrodes.
