Abstract Aqueous zinc‐ion batteries (AZIBs) have emerged as a promising energy storage solution owing to their intrinsic safety, low cost, environmental friendliness, and high theoretical specific capacity. However, practical application is hindered by uncontrollable dendrite growth side reactions at the zinc metal anode. To address these challenges, simple cost‐effective electrodeposition strategy proposed construct quaternary Zn‐Cu‐Sn‐Bi alloy artificial interface layer on foil (ZCSB@Zn) anode of AZIBs. Density functional theory (DFT) calculations in situ optical observation confirm that this dense reduces migration barrier weakens hydrogen adsorption, facilitating uniform deposition while effectively suppressing formation. The symmetric ZCSB@Zn cell exhibits extraordinary cycle stability exceeding 8000 h. Furthermore, assembled ZCSB@Zn//CSB‐MnO 2 full demonstrates capacity 199 mAh g −1 1 A , maintaining even under loading 10 mg cm −2 temperature conditions (50 °C). This study presents scalable for constructing layers anodes, highlighting potential AZIB applications.

Abstract The multi‐electron transfer I − /IO 3 redox couple is attractive for high energy aqueous batteries. Shifting from an acidic to alkaline electrolyte significantly enhances the IO formation kinetics due spontaneous disproportionation reaction, while environment also offers more favorable Zn anode compatibility. However, sluggish during reduction of persists in both and electrolytes, compromising efficiency this glorious couple. Here, we establish fundamental mechanism electrolytes first time propose that Bi/Bi 2 O acts as a mediator (RM) “catalyze” . This mediation reduces voltage gap between charge/discharge 1.6 V 1 with improved conversion rate capability. By pairing RM cathode, full battery achieves areal capacity 12 mAh cm −2 stable operation at 5 over 400 cycles.

Aqueous zinc-ion batteries represent a favorable technology for stationary energy storage systems owing to their safety, reliability, and cost-effectiveness. However, Zn anodes suffer uncontrollable dendrite formation harmful side reactions that lead short lifespan. Herein, we demonstrate nanocluster colloidal electrolyte strategy stabilizing the zinc anodes. A copper (CuNC) is screened out validate efficient suppression of messy dendrites reactions. CuNC could resurface zincophilic protective interlayer interfacially steering uniform stripping/plating mitigating corrosion/hydrogen evolution Impressively, enables show high Coulombic efficiency 99.8% over 2100 cycles extended lifespans 2200 1300 h under 0.5 5 mA cm–2, respectively. full cell based on modified exhibits significantly improved cycling durability more than 15 000 cycles. This work will aid in design nanocluser electrolytes with respect stable chemistry beyond.
