“…[34] Whats more, Zn-air batteries with Fe/OES display an excellent cycling stability (400 cycles) and a substantial elongated lifetime (> 130 h), which is of significance for practical applications. [35] By applying discharging-charging tests, almost no loss of discharging voltage is observed, comparable to that of Pt/C-IrO 2 , exhibiting the outstanding stability of Fe/OES as catalysts (Figures 4 g, S49).…”

“…In fact, as potential alternatives for lithium-ion batteries (LIBs), zinc-air batteries (ZABs) are highly regarded. ZABs offer high theoretical energy density of 1086 Wh/kg (including oxygen) and 1350 Wh/kg (excluding oxygen) which is five times higher than that of current LIBs [3][4][5] . Furthermore, ZABs have a simple design, low operational temperature, high efficiency, high safety and are environmentally friendly 6,7 .…”

Nowadays, due to global warming stemming from excessive use of fossil fuel, there is considerable interest in promoting renewable energy sources. However, because of the intermittent nature of these energy sources, efficient energy storage systems are needed. In this regard, zinc-air flow batteries (ZAFBs) are seen as having the capability to fulfill this function. In flow batteries, the electrolyte is stored in external tanks and circulated through the cell. This study provides the requisite experimental data for parameter estimation as well as model validation of ZAFBs. Each data set includes: current (mA), voltage (V), capacity (mAh), specific capacity (mAh/g), energy (Wh), specific energy (mWh/g) and discharge time (h:min:s.ms). Discharge data involved forty experiments with discharge current in the range of 100-200 mA, and electrolyte flow rates in the range of 0-140 ml/min. Such data are crucial for the modelling and theoretical/experimental analysis of ZAFBs.

Single‐atom catalysts have drawn great attention, especially in electrocatalysis. However, most of previous works focus on the enhanced catalytic properties via improving metal loading. Engineering morphologies of catalysts to facilitate mass transport through catalyst layers, thus increasing the utilization of each active site, is regarded as an appealing way for enhanced performance. Herein, we design an overhang‐eave structure decorated with isolated single‐atom iron sites via a silica‐mediated MOF‐templated approach for oxygen reduction reaction (ORR) catalysis. This catalyst demonstrates superior ORR performance in both alkaline and acidic electrolytes, comparable to the state‐of‐the‐art Pt/C catalyst and superior to most precious‐metal‐free catalysts reported to date. This activity originates from its edge‐rich structure, having more three‐phase boundaries with enhanced mass transport of reactants to accessible single‐atom iron sites (increasing the utilization of active sites), which verifies the practicability of such a synthetic approach.
