To suppress the hydrogen evolution reaction (HER) and dendrite formation on Zn anode in aqueous Zn-ion batteries, a submicrometer In2O3 coating (referred to as Zn@In2O3) was constructed via magnetron sputtering. Density functional theory (DFT) experimental data show that suppresses HER because of its weaker interactions with H* compared Zn, inhibiting Volmer step. At same time, exhibits moderate affinity for Zn*, higher than but lower at In2O3-Zn interface, thus facilitating desolvation hydrated Zn2+ ions while promoting deposition substrate beneath coating. The resultant suppression side reactions growth significantly enhance reversible plating/stripping Zn. optimized Zn@In2O3 stably cycles over 6400 h low voltage hysteresis 9.5 mV 1 mA cm-2 mAh symmetric cells. average Coulombic efficiency is increased from 95.8 99.6% owing Moreover, when coupled Mn0.15V2O5·nH2O cathode, battery maintains capacity retention 78.6% after 2000 5 A g-1. This facile economical modification anodes provides an idea realizing practical application AZIBs.

Abstract Zn‐ion batteries hold significant promise for large‐scale energy storage systems owing to their intrinsic safety and cost‐effectiveness. However, practical deployment is hindered by uncontrolled dendrite growth sluggish electrode reaction kinetics at metallic Zn anodes. To overcome these limitations, a quasi‐solid electrolyte (M@Z) based on MOF@ZnIn 2 S 4 composite presented. This innovative exhibits high room‐temperature conductivity (0.99 mS cm −1 ) an improved 2+ transference number (0.54). The microporous MOF component ensures uniform deposition effectively suppresses formation. Meanwhile, the ZnIn nanosheets wrapped around particles promote formation of beneficial In/ZnS‐contained interphase anodes during cycling, which mitigates side reactions accelerates anode kinetics. By virtue above merits, symmetric cells achieve stabilized plating/stripping over 3130 h with low overpotential tolerate critical current density 10 mA −2 . Furthermore, vanadium‐based full assembled M@Z deliver exceptional cycling stability, almost no capacity decay after 1000 cycles 1.0 A g
