“…Up to now, various Zn‐based batteries have been widely investigated, such as Zn–air battery,10–13 Zn–NiOOH battery,14–16 Zn–V 2 O 5 battery,17–19 Zn–MnO 2 battery,20–23 etc. However, besides the dendrite growth in the electrolyte, the Zn anode corrosion and the formation of ZnO densification on the Zn electrode surface have become the challenges for the development of rechargeable Zn‐based batteries, which would result in poor reversibility, low Coulombic efficiency (CE), and the decayed capacity 24. Regarding the corrosion of Zn anode, it can happen during the charge/discharge processes of Zn batteries.…”

In an aqueous Zn‐based battery, it is expected that this surface coating can suppress HER for eliminating Zn corrosion and ZnO densification, providing more controllable nucleation sites for Zn 2+ , and facilitate the fast ion kinetics of electrochemical reactions.…”

Aqueous Zn batteries have drawn tremendous attention for their several advantages. However, the challenges of Zn anodes such as the corrosion and ZnO densification have compromised their application in rechargeable Zn‐based batteries. In this paper, a straightforward strategy is employed to facilitate the uniform Zn stripping/plating of the Zn anode through using a ZrO2 coating layer, which contributes to the controllable nucleation sites for Zn2+ and fast Zn2+ transportation through the favorable Maxwell–Wagner polarization. As a result, the low polarization (24 mV at 0.25 mA cm−2), high Coulombic efficiency (99.36% at 20 mA cm−2), and long cycle life (over 3800 h at 0.25 mA cm−2) can be obtained for the ZrO2‐coated Zn anode. It is believed that the ZrO2 coating layer can also act as an inert physical barrier to decrease the contact of the anode and electrolyte, thus reducing both the Zn corrosion and formation of ZnO densification, and then improve the reversibility of Zn anode. The results demonstrated in this work provide an appealing strategy for the future development of rechargeable Zn‐based batteries.

Rechargeable zinc–air batteries are considered as next‐generation energy storage devices because of their ultrahigh theoretical energy density of 1086 Wh kg−1 (including oxygen) and inherent safety originating from the use of aqueous electrolyte. However, the cathode processes regarding oxygen reduction and evolution are sluggish in terms of kinetics, which severely limit the practical battery performances. Developing high‐performance bifunctional oxygen electrocatalysts is of great significance, yet to achieve better bifunctional electrocatalytic reactivity beyond the state‐of‐the‐art noble‐metal‐based electrocatalysts remains a great challenge. Herein, a composite Co3O4@POF (POF=framework porphyrin) bifunctional oxygen electrocatalyst is proposed to construct advanced air cathodes for high‐performance rechargeable zinc–air batteries. The as‐obtained composite Co3O4@POF electrocatalyst exhibits a bifunctional electrocatalytic reactivity of ΔE=0.74 V, which is better than the noble‐metal‐based Pt/C+Ir/C electrocatalyst and most of the reported bifunctional ORR/OER electrocatalysts. When applied in rechargeable zinc–air batteries, the Co3O4@POF cathode exhibits a reduced discharge–charge voltage gap of 1.0 V at 5.0 mA cm−2, high power density of 222.2 mW cm−2, and impressive cycling stability for more than 2000 cycles at 5.0 mA cm−2.

The optimization of electrolyte flow management to increase the performance of Zn–air fuel cells

Summary Zinc (Zn)–air fuel cells (ZAFCs) are one of the potential alternatives to fossil fuels. Because a flowing electrolyte can directly affect cell performance, we focused on the electrolyte management of a ZAFC. The ZAFC galvanostatic discharge was examined to determine its performance. The electrolyte concentration, temperature, and circulation rate were used as the operating parameters for discharge tests, and the relationship between electrolyte and cell performance was discussed based on the experimental results. To elucidate the effect of electrolyte‐flow, the computation fluid dynamic simulations have been first performed. The results revealed that the cell performance associating the remnant oxygen in the electrolyte channel
