Current status and technical challenges of electrolytes in zinc–air batteries: An in-depth review

Abstract: In the past few years, there has been a growing level of interest in the research and development of energy storage systems such as batteries. This is a direct consequence of the soaring rise in global energy demand across various commercial and industrial sectors. Lithium ion batteries have set out a feasible horizon for widespread deployment as small-scale energy storage devices due to their high efficiency and cyclability. However, the availability and cost of lithium have limited the commercial deployment … Show more

“…However, insufficient studies on the development of suitable electrolyte and influencing factors, such as its composition, delayed the erudite understanding of the matter despite the cell discharge potential, rechargeability, and cell performance having direct implications on the electrolyte. An apt electrolyte should possess high ionic conductivity (>10 −4 S/cm) and low electronic conductivity (<10 −10 S/cm), high chemical stability, low cost and be non‐hazardous to humans and the environment 104 . In general, aqueous electrolytes, such as alkaline solutions, are typically employed owing to the desirable ionic conductivity of cation ions, such as K + , Li + , Na + , and Mg 2+ ; in addition, the development of new electrolytes is scarce.…”

“…Adding gel to an aqueous electrolyte increases viscosity, eliminating leakage and leading in the suspension of zinc powder. 53 The zinc-air cell was developed using a zinc foil as the anode, an active perovskite catalyst containing nickel foam as cathode, and 6 M KOH and 0.2 M Zinc Acetate soaked in PVA as an electrolyte, as shown in Figure 6A. Further, Figure 6B interprets the galvanodynamic plot of current density versus voltage polarization for the rechargeable zincair battery cell.…”
