Aqueous zinc-ion batteries have attracted intensive attention because of their safety, low cost, and high theoretical capacity; however, practical application is hindered by challenges, such as Zn dendrite formation, the hydrogen evolution reaction, a limited cycle life. Herein, zinc anode interface prepared combining sodium alginate (SA) with hydroxyl carboxyl groups binder zeolite imidazole framework (ZIF-7) ion transport channel. The in SA exhibit strong Zn2+-ion affinity, forming cross-linked structure ZIF-7 creating self-reinforcing coating that promotes uniform Zn2+ flux while provides suitable ionic channels to enable oriented deposition. A ZIF-7/SA coated (ZIF-7/SA@Zn) exhibited Coulombic efficiency 99.7% after 1500 cycles at 10 mA cm-2 1 h cm-2. Even under high-current high-capacity conditions (20 cm-2, 20 cm-2), ZIF-7/SA@Zn maintained stable cycling for 500 h. When was paired Zn0.25V2O5 cathode, resultant full cell retained more than 77.2% its capacity 10,000 3000 g-1. This work proposes strategy stabilize anodes currents, advancing high-performance Zn-based energy storage systems.

Zinc-ion batteries become a major research focus in energy storage, valued for their low cost and high safety. However, widespread application is hindered by poor zinc anode stability caused dendrites, side reactions, performance across wide temperature range at strong hydrogen bond network aqueous electrolyte. In this study, we propose strategy the synergistic combination of polyacrylamide hydrogel with sucrose. The experimental theoretical results demonstrate that through effect sucrose, they regulate solvation structure Zn2+ inhibit interfacial reactions active water. Zinc corrosion dendrite growth issues were also effectively mitigated effect. Consequently, Zn//Zn-symmetric battery achieved stable cycling exceeding 6240 h room 0.5 mA cm–2 mAh cm–2. Zn//VO2 full has good stability, maintaining cycle even temperatures (10,000 cycles 1 A g–1 0 °C). Even −10 °C, it (Zn//Zn-symmetric more than 3970 h). This work provides an alternative developing low-cost, electrolytes zinc-ion batteries.

Abstract The side reactions and dendritic growth largely impede the utilization of Zn anode in aqueous zinc ion batteries (AZIBs). Herein, a novel strong acidic electrolyte additive itaconic acid (IA) is introduced to achieve highly stable via dual functions. First, use trace amounts IA can provide steady low pH environment for electrolyte, which beneficial eliminate alkaline by‐products by neutralizing OH − that accumulated near anode. Second, an interfacial protective layer be situ formed cross‐linking reduction reaction between anode, helping inhibit continuous corrosion on promote formation uniform deposition. Consequently, achieves ultra‐long cycle‐life (5390 h at 1 mA cm −2 , mAh ) enhanced coulombic efficiency (99.86% upon 2100 cycles 5 −1 ). Besides, full cell assembled with sodium vanadate delivers high reversible capacity 179.6 g over 2000 2 A . This work offers new solution related insights design electrolytes additives toward AZIBs.
