“…There are many efforts devoted to solve these problems up to now, which are mainly focused on the stabilization of zinc anode interface and the design of more stable cathode materials, respectively. − In addition to these structural modification strategies, electrolyte optimization is an effective approach. Developing functional electrolyte additives is a versatile method to change the coordination environment of an aqueous electrolyte. − However, most of them are currently aimed at the protection of a single zinc anode and may be excessively adsorbed on the electrode during cycling, thereby increasing polarization of electrode and delay the charge-transfer process .…”

Aqueous zinc-ion batteries (ZIBs) suffer from dendrite growth, hydrogen evolution reaction (HER), and cathode dissolution. To overcome the above issues, we designed a single Zn2+ conductor hydrogel electrolyte (poly 3-sulfopropyl acrylate zinc, PSPAZn) through UV photopolymerization of the designed monomer zinc salt of SPAZn. The polymerized and fixed anion chains with single Zn2+-conducting characteristics not only promote the uniform distribution of Zn2+ ion flux by charge interaction but also decrease the concentration polarization, leading to nondendrite Zn deposition behavior. Meanwhile, the water activity is significantly reduced due to abundant hydrophilic groups in polymer side chains, effectively inhibiting HER and the dissolution of cathode materials. Consequently, the lifespan of a zinc anode with PSPAZn electrolyte is extended to more than 3000 h, and the Zn/MnO2 full ZIBs also exhibit a high capacity retention of 77.1% after 220 cycles without MnSO4 additive. Such a simple kilogram-scale preparation strategy should offer opportunities for developing practical ZIBs.

“…Also, porous Zn can reduce the gas evolution and improve the depth of discharge (DOD). [ 41 ] Parker et al. [ 39 ] designed a sponge zinc with ZnO layers in the cavities to stabilize the interface, and obtained more than 100 cycles at a DOD of 40% with no gas evolution (Figure 6d).…”

Aqueous Zn‐ion batteries (AZIBs) have attracted much attention due to their excellent safety, cost‐effectiveness, and eco‐friendliness thereby being considered as one of the most promising candidates for large‐scale energy storage. Zn metal anodes with a high gravimetric/volumetric capacity are indispensable for advanced AZIBs. However, pristine Zn metal anodes encounter severe challenges in achieving adequate cycling stability, including dendrite growth, hydrogen evolution reaction, self‐corrosion, and by‐product formation. Because all these reactions are closely related to the electrolyte/Zn interface, the subtle interface engineering is important. Many strategies targeted to the interface engineering have been developed. In this review, a timely update on these strategies and perspectives are summarized, especially focusing on the controllable synthesis of Zn, Zn surface engineering, electrolyte formulation, and separator design. Furthermore, the corresponding internal principles of these strategies are clarified, which is helpful to help seek for new strategies. Finally, the challenges and perspectives for the future development of practical AZIBs are discussed, including the conducting of in advanced in situ testing, unification of battery models, some boundary issues, etc. This review is expected to guide the future development and provi beacon light direction for aqueous zinc ion batteries.

Rechargeable batteries have gained a lot of interests due to rising trend of electric vehicles to control greenhouse gases emissions. Among all type of rechargeable batteries, lithium air battery (LAB) provides an optimal solution, owing to its high specific energy of 11,140 Wh/kg comparable to that of gasoline 12,700 Wh/kg. However, LABs are not widely commercialized yet due to the reactivity of the lithium anode with the components of ambient air such as moisture and carbon dioxide. To address this challenge, it is important to understand the effects of moisture on the electrochemical performance of LAB. In this review, the effects of ambient air on the electrochemical performance of LAB have been discussed. The literature on the deterioration in the battery capacity and cyclability due to operation in ambient environment and degradation of lithium anode due to exothermic reaction between lithium and water is reviewed and explained. The effects of using oxygen-selective membrane (OSM) to block moisture and $${\mathrm{CO}}_{2}$$ CO 2 contamination has also been discussed, along with suitable materials that can act as OSM. It is concluded that the utilization of OSM can not only make the safer operation of LAB in ambient air but could also enhance the electrochemical performance of LAB. Future direction of the research work required to address the associated challenges is also provided.
