“…6,7 Although highperformance cathodes have been developed to overcome the above-mentioned problems, [8][9][10] the electrolyte also directly affects the performance of ZIBs. 11 Concentrated salt and other additives (organic solvents and ionic liquids) [12][13][14][15] were incorporated in aqueous electrolytes by tuning the solvation sheath of Zn 2+ to promote the plating/stripping and migration of Zn 2+ . 16 However, the water-induced side reactions are inevitable, and thus the development of new electrolytes without water, such as organic electrolytes and solid (or quasi-solid) electrolytes, is very important.…”

“…The electrochemical performances of zinc anode with various organic solvent additives are summarized in Table 2. 17,79,170,174,176–178,184,186–195,202–205 Generally, these organic solvent additives always show excellent solubility in water and can preferentially solvate with Zn 2+ ions. Besides, they have a strong interaction with H 2 O, which can reduce the activity of free H 2 O molecules.…”

“…Except the inorganic additives, various kinds of small molecule organic compounds have also been reported as the electrolyte additive to enhance the electrochemical performances of ZIBs. [86][87][88][89][90][91][92][93][94] It has been reported that different molecular structure and functional groups play various roles. For example, polar substances electrostatically attached adjacent to the surface of the initial protuberant zinc tips can further hinder zinc ion deposition.…”

future is not such bright. Therefore, the drawbacks of these organic-based batteries systems motivate us to explore the alternative battery with low-cost, high safety, and long-cycle-life. [20][21][22][23] Compared to nonaqueous batteries, aqueous batteries have the advantages of low cost, better safety, high ionic conductivity, easy processing, low manufacturing cost, etc., so that they are in a better position for large-scale energy storage applications. [24][25][26][27][28] Among them, the aqueous ZIBs have attracted tremendous attention due to their distinct advantages, that is, high gravimetric and volumetric capacity (820 mAh g −1 , 5855 mAh cm −3 ) offered by Zn metal, low redox potential of zinc (−0.763 V vs a standard hydrogen electrode), good stability of zinc metal in water compared to the extremely active lithium, sodium and potassium metals, as well as its highlighted low cost and natural abundance. [3,[29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] Nevertheless, aqueous ZIBs still face several challenges that hinder their wider utilization: i) the dissolution of cathode materials and obstacles of intercalating into the host materials; [29,30] ii) the irreversible Zn stripping/plating process caused by formation of Zn dendrites and corrosion on the anode; [31,34,35,37,46] iii) the narrow electrochemical window in aqueous electrolyte; [30,33,36] iv) sluggish transport and solvation/desolvation of Zn 2+ . [15,36] All of them impact the capacity, life cycle, and rate property of aqueous ZIBs.Aqueous zinc ion batteries (ZIBs) are regarded as one of the most ideally suited candidates for large-scale energy storage applications owning to their obvious advantages, that is, low cost, high safety, high ionic conductivity, abundant raw material resources, and eco-friendliness. Much effort has been devoted to the exploration of cathode materials design, cathode storage mechanisms, anode protection as well as failure mechanisms, while inadequate attentions are paid on the performance enhancement through modifying the electrolyte salts and additives. Herein, to fulfill a comprehensive aqueous ZIBs research database, a range of recently published electrolyte salts and additives research is reviewed and discussed. Furthermore, the remaining challenges and future directions of electrolytes in aqueous ZIBs are also suggested, which can provide insights to push ZIBs' commercialization.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/smll.202104640.
