Abstract Aqueous zinc‐ion batteries (AZIBs) have great potential for large‐scale energy storage applications. However, the parasitic reactions, such as continuous hydrogen evolution reaction (HER), seriously hamper reversibility and cycling stability of zinc metal anode (ZMA), limiting its practical application. In this paper, a pre‐growth interfacial layer strategy is adopted to grow enol/ketone conversion on surface ZMA (denoted Zn@AA). H + can be reversible “lock/unlock” during reaction. It not only broadens capacity AZIBs (Zn 2+ /H co‐insertion), but also inhibits HER (the amounts 2 decreased obviously in both Zn@AA||Zn@AA Zn@AA||VO ·H O@Ppy (Ppy denote polypyrrole) cells by on‐line differential electrochemical mass spectrometry analysis), thereby improving performance. The cycle life assembled cell exceeded 3200 h at 1 mA cm −2 . Furtherly, full exhibited excellent retention. This work provides new ideas modifying inhibit HER, which guides development AZIBs.

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.
