The commercial traditional energy storage devices such as lithium-ion batteries and sodium-ion batteries are bulk and stiff, which hardly meet the requirements of flexible and wearable electronics. [2] Thus, seeking the power sources with high safety, reliability, and flexibility is highly urgent. [3] Aqueous zinc-ion batteries (AZIBs) have attracted a lot of interests with the features of inherent safety, plentiful reserves, low standard redox potential of Zn/Zn 2+ of −0.76 V versus the standard hydrogen electrode (SHE), and facile fabrication process. [4] Besides, the mild or weak acid aqueous electrolytes deliver higher conductivity and safety than organic electrolytes, implying the favorable power density of AZIBs. [5] These virtues endow the AZIBs present marvelous potential application in flexible electronic devices, under a condition that the AZIBs possess excellent flexibility via adopting flexible current collector and flexible packaging materials. [6] However, when the flexible AZIBs based on liquid electrolyte undergo various mechanical deformations, the occurrence of electrolyte leakage may jeopardize the cyclic performance of the batteries. [7] Moreover, the aqueous liquid Aqueous zinc-ion batteries (AZIBs) may have applications in macroscale energy storage on account of their advantages of high-safety, cost-effectiveness, and ecofriendliness. As a promising application, flexible quasi-solidstate AZIBs (FQAZIBs) can withstand mechanical deformation, and can act as favorable power supply devices for wearable electronics. As FQAZIBs are one of the most exciting and rapidly ongoing topics among aqueous batteries, it is critical yet timely to summarize the latest development in this field, providing the much-needed guidance for the fabrication of FQAZIBs. In this review, the recent progress and rational design strategies for FQAZIBs from mechanisms, design principles, and applications are systematically presented. First, the energy storage and flexible mechanisms of FQAZIBs are illuminated in detail. Subsequently, the design philosophies of FQAZIBs are also systematically elucidated. Moreover, the latest progress and practical applications of FQAZIBs in wearable electronics are reviewed in detail according to various functions such as compressibility, stretchability, electrochromic ability, anti-freezing ability, self-healing ability, self-charging properties, photodetecting function, shape memory, biodegradability, and actuated function. Finally, some applications and promising prospects in the research area of FQAZIBs are demonstrated to supply guidelines on the exploitation of their practical applications.

“…Although rechargeable aqueous batteries are attracting increasing attentions due to their low cost, high safety, environmentally friendly nature, and improved rate performance, the "free water" (the term "free water" indicates water molecules interacting solely with other water molecules) [139] molecules in aqueous electrolytes strongly limit the electrochemical stability window of the electrolyte and trigger multiple side reactions, thus affecting cell performance upon cycling. In order to suppress the activity of "free water" molecules and expand the electrochemical stability window, novel electrolytes and components have been proposed, including high concentrated electrolytes or "water-in-salt/gel" electrolytes, [78,82,87,95,97,105,107,140] hybrid electrolytes, [65,66,74,75,77,78,[81][82][83]85,87,95,107,141,142] solid polymer electrolyte, [103] and additives, [84,86,88,89] to improve the electrochemical performances of AZIBs. D. Kim et al [140] reported that the cycling performance of ZnHCF in concentrated electrolyte (3 M Zn(NO 3 ) 2 ) was superior to that observed in the diluted system (1 M Zn(NO 3 ) 2 ), as a consequence of the decrease in the hydration number and radius of the zinc ions in the concentrated electrolyte.…”

Aqueous zinc‐ion batteries (AZIBs), have been identified as one of the most promising aqueous rechargeable metal‐ion batteries (ARMIBs) for grid scale electrochemical energy storage application, and as such have received much attention by virtue of their unique properties including the high abundance of metallic zinc resources, their intrinsic safety, and cost effectiveness. Among the cathode materials used in AZIBs, Prussian Blue Analogues (PBAs) represent the most promising active materials in view of their improved cyclability and rate performance. Here we provide a comprehensive review on recent progress on AZIBs obtained using PBAs cathodes with a particular focus on the present understanding of the structure‐property correlation of different PBAs, which in turn guides further developments of improved cathode materials and optimization strategies to ensure an extended cyclability and capacity retention.

“…[1][2][3][4] In this regard, aqueous zinc-ion batteries (ZIBs) have recently received attention due to their intrinsic advantages, including high safety, low cost, and environmental friendliness. [5][6][7][8][9][10] Different types of cathode materials, including manganese oxides, [11][12][13][14][15] vanadium oxides, [16][17][18][19][20][21] Prussian blue analogs, [22][23][24] and even organic cathodes, [25][26][27] have been widely utilized in the ZIBs, among which, vanadate-based cathodes, especially V 2 O 5 -originated species, have been extensively studied. Specically, because of the multivalent property, the open layered structure, and the support from the intercalated cations, V 2 O 5 -based materials can store more Zn 2+ to provide higher capacity.…”
