“…30 It is reported that ZnF 2 possesses high ionic conductivity, which is an effective component in the construction of stable electrode/ electrolyte interface. 31,32 Moreover, the SEM images and XRD patterns of PW and PW-5 wt % ZnO electrodes after 200 cycles were investigated (Figures S7 and S8). PW-5 wt % ZnO exhibits an intact particle without microcracks, as depicted in Figure S7a.…”

Iron-based Prussian white (PW) is one of the promising cathodes for sodium-ion batteries, owing to its high capacity and low cost. However, the practical application of PW is hindered by its poor air stability. The metal-oxide coating has been proven to be an effective way to improve the air stability of electrode materials. Whereas, the target electrode materials conventionally need to be dissolved in the aqueous solution to obtain precursor composites and subsequently calcined at a high temperature during the metal-oxide coating process, which could destroy the phase structure of PW as a result of the sodium leaching into the water and thermal decomposition at the high temperature. In this work, we propose a facile method to construct a ZnO surface layer on PW by utilizing ethanol as a solvent and a mild post-treatment temperature. The ZnO coating layer effectively enhances the air stability of PW and induces the formation of the stable interface on PW. The PW-5 wt % ZnO-E (exposed in 60% humidity air after 30 days) cathode demonstrates a much higher capacity retention (94.1%) at 1 C after 200 cycles than that of PW-E (54%). This work lays a solid foundation for further application of PW.

“…The preparation process of artificial CEIs is often complex, and their stability during the cycling process is rarely mentioned. 35 Based on these facts, it is crucial to construct a stable cathode from bulk phase to surface for advanced AZIBs. To date, there are few effective strategies for this kind of cathode to simultaneously realize bulk-phase structural stability and stable surfaces.…”

“…The second strategy focuses on kinetically suppressing the electrolysis of electrolytes by fostering the growth of electrolyte interphases on electrodes. [5] This approach takes inspiration from the successful formation of solid electrolyte interphase (SEI) on anodes and cathode electrolyte interphase (CEI) on cathodes in lithium-ion batteries. It is important to note that the names SEI and CEI may not align semantically, potentially confusing newcomers.…”

The narrow electrochemical stability window of water poses a challenge to the development of aqueous electrolytes. In contrast to non‐aqueous electrolytes, the products of water electrolysis do not contribute to the formation of a passivation layer on electrodes. As a result, aqueous electrolytes require the reactions of additional components, such as additives and co‐solvents, to facilitate the formation of the desired solid electrolyte interphase (SEI) on the anode and cathode electrolyte interphase (CEI) on the cathode. This review highlights the fundamental principles and recent advancements in generating electrolyte interphases in aqueous batteries.
