Abstract An effective strategy to facilitate oxygen redox chemistry in metal‐air batteries is introduce a mediator into the liquid electrolyte. The rational utilization of mediators accelerate charging kinetics while ensuring long lifetime alkaline Zn‐air challenging. Here, we apply commercial acetylene black catalysts achieve an I 3 − ‐mediated battery by using ZnI 2 additives that provide cathodic and regulate uniform deposition Zn 2+ on anode. performs ultra‐long cycle life over 600 h at 5 mA cm −2 with final charge voltage 1.87 V. We demonstrate mainly generates surface carbon during electrochemically process, which can further chemically react OH generate revert , thus obtaining stable electrochemical system. This work offers simultaneously improve cycling reduce through methods.

Abstract Aqueous zinc‐ion batteries (AZIBs) are emerging as a promising energy storage technique supplementary to Li‐ion batteries, attracting much research attention owing their intrinsic safety, cost economy, and environmental friendliness. However, densities for AZIBs still do not fulfill practical requirements because of the low specific areal capacity, limited working potential, excessive negative‐to‐positive electrode capacity (N/P) ratio. In this review, comprehensive overview basic major challenges achieving high‐energy‐density is provided. Following that, recent progress in optimization each component overall configuration summarized, crucial design principles discussed. Apart from conventional emphasis on part, especially cathode materials, separately, discussion about synergistic interactions among all components conducted. Finally, outlook direction given provide valuable guidance further holistic development aqueous batteries.
