They use mildly acidic and near neutral (pH = 3–5) aqueous Zn-salt solutions as electrolyte, Zn-metal as anode, and layered/open framework compounds as cathode.
This study reveals the impact of dissolved oxygen in electrolytes on zinc-ion batteries. However, more rigorous analyses and evidence, such as in-situ or in-operando experiments, are needed for a complete understanding of the reaction mechanism of oxygen on zinc-ion batteries. All methods can be found in the accompanying Transparent Methods supplemental file.
Zn–oxygen batteries use Zn as an anode instead of Li, (7) despite allowing a narrower difference of potential than Li-oxygen batteries using organic electrolytes. The use of Zn enables the use of safer and nonflammable aqueous electrolytes and reduces the stability risks in comparison with other metal–air configurations.
The dissolved oxygen in the aqueous electrolytes of ZIBs might oxidize the Zn anode, impacting the performance of the devices. However, there is limited research on the influence of dissolved oxygen in electrolytes on the electrochemical properties of aqueous ZIBs.
Due to their high safety, low cost, eco-friendliness, and impressive electrochemical performance, rechargeable zinc-ion batteries (ZIBs) show great potential as electrical energy storage devices for large-scale applications. Nonetheless, recently developed ZIBs still suffer from low cycling stability and high capacity fading.
The use of Zn enables the use of safer and nonflammable aqueous electrolytes and reduces the stability risks in comparison with other metal–air configurations. (8) Zn–oxygen batteries have a high energy density of around 1086 Wh/kg that is mainly achieved through two reactions: Oxygen Reduction Reaction (ORR) and Oxygen Evolution Reaction (OER).
