“…[ 19f ] Consequently, it is desired that Zn crystal should grow along the (002) direction to form Zn plates that are parallel to the substrate surface ( Figure 4 a,b). [ 19f,35 ] Therefore, Zn crystal growth needs to be regulated to reduce the energy barrier of crystal growth along (002) direction but increase the energy barrier of growth in other directions.…”

“…For instance, graphene oxide (GO) was decorated on glass fiber (GF) separator via a facile vacuum filtration method for this purpose. [ 35 ] Compared with the pristine GF membrane, the GO‐modified GF separator leads to preferential Zn deposition along the (002) direction. Correspondingly, the unfavorable Zn dendrites, which are perpendicular to the anode surface, could be minimized even at a large Zn plating current density of 20 mA cm –2 .…”

scenario, the utilization of alternative and sustainable energy types, such as solar energy, [2] wind energy, [3] biomass energy, [4] tidal energy, [5] and geothermal energy, [6] is essential. Although these types of energy are generally accessible and clean, the direct storage and transportation of them are extremely difficult, and their highly fluctuating nature makes things even worse. [7] Alternatively, electrical energy is often generated from these energy types and serves as an intermediate between the direct energy harvest and the terminal utilization. In this regard, the development of energy storage systems (ESSs) is essential to provide a more versatile and stable energy supply for individual, household, and industrial applications, which has consequently been extensively investigated. [8] Among all current ESSs, batteries play a major role [9] and have been indispensably utilized for portable electronics, tools, electric vehicles (EVs), and even power grids. [10] Owing to their lightweight, high energy density, and extended cycle life, lithium-ion batteries (LIBs), initially developed in the early 1990s, are regarded as a milestone of ESS technologies. [11] Since then, LIBs have been widely applied, which have reshaped our lifestyle. Despite their success in mass production, commercial LIBs still suffer from high cost due to the limited lithium resource and the high cost of other components (e.g., Co-based cathode), [12] which is further worsened by the rigid requirement for their manufacture. Besides, the safety concerns, which stem from the flammable organic electrolyte and highly reactive lithium species, also significantly hinder the deployment of LIBs on a large scale. [13] Considering these limitations of LIBs, it is necessary to develop alternative ESSs with comparable energy/power density but better costeffectiveness and higher safety characteristics. [14] To achieve this, the exploration of high capacity yet relatively inert anode materials and nonflammable electrolytes is essential. Zinc-ion batteries (ZIBs) have been prospected as a new generation of inexpensive and safe ESS devices. Different from typical LIBs, a ZIB is composed of a Zn 2+ ion storage cathode and a Zn metal anode, which is favorable for high anode capacity. Furthermore, aqueous electrolytes are frequently used for ZIBs rather than the organic ones. [15] As a result, energy is stored and released via the reversible Zn stripping/plating at the anode and Zn 2+ insertion/desertion at Zinc-ion batteries (ZIBs) are regarded as a promising candidate for next-generation energy storage systems due to their high safety, resource availability, and environmental friendliness. Nevertheless, the instability of the Zn metal anode has impeded ZIBs from being reliably deployed in their proposed applications. Specifically, dendrite formation and the hydrogen evolution reaction (HER) on the Zn surface significantly compromise the Coulombic efficiency and cycling stability of ZIBs. In recent years, increasing efforts have been devoted t...

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 of large-scale systems. On the other hand, zinc-air batteries have demonstrated comparable efficiencies and have been reported to be suitable replacements for lithium batteries in large-scale applications. Nevertheless, more research has been undertaken to address the issues associated with the cycling processes of these batteries. Secondary zinc-air batteries are yet to be commercially proven feasible due to the low charge/discharge cycle life of electrodes. The main problems of secondary alkaline zinc-air batteries are dendritic growth resulting in an alternation of morphology and structure, self-dissolution and the consequent occurrence of hydrogen evolution reactions. However, by and large, inefficient electrolytes are the main culprits responsible for the reduced performance of zinc-air batteries. Therefore, a comprehensive review of current advancements in the development of suitable electrolytes to promote zinc-air batteries towards commercial application will provide a perspective for future rechargeable zinc-air batteries. In this in-depth review, the effects of the types of electrolytes and their properties on the electrochemical 2 performance of Zn anode have been discussed. A demonstration of the current research status and challenges set upon the large-scale deployment of zinc-air batteries will facilitate the educated steering of future research directions in this critically important realm.
