Abstract Despite aqueous electrolyte endowing batteries with the merits of safe operation, low‐cost fabrication, and high ionic conductivity, water‐induced corrosion, including spontaneous chemical electrochemical hydrogen evolution adversely affects lifespan rate capability. There is still a lack selection criteria for benchmarking corrosion behavior qualitatively. Through theoretical simulation, an anionic polarity index (API) tactic proposed to resist by manipulating interfacial solvated water concomitantly, thus realizing stable fast Zn (ZABs). As proof concept, zinc salt 0.5 m bis(4‐hydroxybenzenesulphonate) (Zn(HBS) 2 ) low‐API anion prioritized. Combined in situ spectroscopic analyses reveal that, even low‐concentration electrolyte, reduces inner Helmholtz plane, shielding dissociation. Meanwhile, their entering into solvation sheath 2+ lowers solvent‐separated ion pair, suppressing corrosion. The elaborated API‐screened endows plating kinetics 50 mA cm −2 (119.1 mV polarization), coulombic efficiency 99.8%, dendrite‐free cycling over 1600 h, prolonged 5000 cycles Zn‐V cell. results provide new metrics that can benchmark success ZABs large‐scale energy storage.

Abstract The design of anode‐free zinc (Zn) batteries with high reversibility at areal capacity has received significant attention recently, which is quietly challenging yet. Here, a Zn alloyed interface through electroplating introduced, providing homogeneous prenucleation sites to stabilize subsequent nucleation and plating. By employing Zn–Cu alloy as module, the complementary simulations characterizations confirm that interfaces achieve electric field distribution greatly enhance stability anode. Accordingly, Zn//Zn–Cu@Cu half‐cells show long cycle life over 900 h an average Coulombic efficiency (CE) 99.8% 10 mAh cm −2 . assembled zinc–bromine (Zn–Br 2 ) battery exhibits attractive stable cycling 11 000 cycles 1 , while 1000 higher Excitingly, Zn–Br pouch cell operates stably 50 cycles, achieves successful integration photovoltaic systems. This constructed strategy offer new insights into potential for large‐scale energy storage applications.

Abstract The undesirable hydrogen evolution reaction (HER) primarily contributes to the instability of Zn anode, which exacerbates corrosion and dendrite growth impedes application metal battery in large‐scale energy storage. Although engineering functional aqueous electrolyte prominently controls HER, it hardly eradicates occurrence HER from source.

PC molecules acceptor strengthen H‐bonds networks between MeOH donor weaken interaction cations anions, enhancing stability reducing anion‐involved by‐products formation. Meanwhile, preferential adsorbed on anode surface form favorable component‐dominated solid interface layer, inducing uniform deposition along (002) orientation.

Abstract The practical application of zinc (Zn)–air batteries is largely restricted by their inferior cyclability, especially under fast‐charging conditions. Uneven Zn plating and dendrite formation result in short circuits. In this work, an artificial solid‐electrolyte interphase (SEI) constructed using indium–organic frameworks (IOF) on the anode. It contains a hybrid architecture that integrates chemical morphological contributions to regulate behaviors constrain growth. atomically dispersed 3+ provides zincophilic sites tune nucleation kinetics promote preferential growth along (002) crystal facet. Meanwhile, IOF exhibits nanosheets‐assembled microspheres with well‐ordered porous architecture, which promotes mass transfer affords space for electrodeposition. influence SEI microstructure plating/stripping behavior further investigated validated post‐cycling characterizations. With based SEI, symmetric cells perform stable cycling over 1750 h at 10 mA cm −2 . When powering Zn–air batteries, life extended 800 h, approximately four times longer than pristine foil.
