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. Herein, this research utilizes coupling donor–acceptor bonds (H‐bonds) manipulate structure design a novel methanol (MeOH)‐based anhydrous organic with propylene carbonate (PC) as co‐solvent, fundamentally eliminating accompanied by suppressed growth. 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. Consequently, exhibits excellent cycling high reversibility. assembled cells also harvest satisfactory low‐temperature tolerance. More importantly, corresponding Zn||PANI full cell pouch behave an impressive capacity retention 92.4% 91.1% after 3200 1400 cycles, respectively.

The aqueous zinc-ion battery (AZIB) is regarded as one of the most promising energy storage solutions. However, its widespread adoption hindered by challenges such zinc dendrite formation and undesirable side reactions, primarily caused excess free water molecules ions. This study introduces an ethylene oxide (PEO)-based gel electrolyte designed to address these limitations. By incorporating a zinc-rich ionic conductor (TP-Zn) that establishes cross-linked hydrogen bond network, we successfully reduce crystallinity PEO matrix enhance conductivity mechanical strength electrolyte. resulting PGPS@TP-Zn exhibits remarkable tensile deformation up 1785%. incorporation TP-Zn significantly alleviates interfacial between electrode, leading more uniform ion flux distribution. This, in turn, improves transport kinetics, high 1.32 × 10–3 S cm–1 transference number 0.86. Furthermore, Zn||Zn symmetrical cell shows exceptional stability when using PGPS@TP-Zn, with cycle life exceeding 3000 h at current density 1 mA cm–2 capacity mAh cm–2. In addition, Zn||PGPS@TP-Zn||α-MnO2 full maintains retention 76.9% even after 1000 cycles 2 A g–1. Remarkably, assembled pouch functions normally bent maximum angle 180 degrees. highlights significant practical advantages design for advanced AZIB applications.

Abstract The vulnerable Zn electrode interface with uncontrolled dendrite growth and severe parasitic side reactions constrains the practical application of aqueous zinc‐ion batteries (AZIBs). General engineering offers a promising approach to relieve these issues but is limited by confined functionality, low affinity, additional weight protective layer.

This multiple process contributed accelerated [Zn(H 2 O) 6 ] stabilized transport, inhibited reactions. Consequently, dendrite‐free highly reversible SF@Zn anodes are realized, exhibiting an ultra‐long lifetime (more than 4300 h), high Coulombic efficiency (CE) (99.1% after 2600 cycles), superior full cell capacity retention (83.2% 1000 cycles). innovative strategy provides novel method enhance anode stability via molecular‐level design multicomponent reaction, offering new insights into advanced for AZIBs.
