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.
