“…[ 2 ] Recently, extensive attention have been paid to aqueous batteries due to the merits of high power density, safe operation, and inexpensive nature. [ 3 ] Among recently reported aqueous batteries, rechargeable aqueous zinc‐based batteries (AZBs) have attracted great interest due to the following advantages of metallic zinc: 1) the high theoretical capacity (≈820 mA h g −1 ) and theoretical volume capacity (5854 mA h cm −3 ); 2) the suitable standard redox potential of Zn/Zn 2+ (−0.76 V vs the standard hydrogen electrode (SHE)) and being chemically stable in air; 3) the relatively lower polarizability compared with other metals (e.g., Mg and Al); and 4) the high natural abundance. [ 4–6 ] Moreover, the electrolytes used in AZBs are usually cheap, such as ZnCl 2 and ZnSO 4 .…”

Rechargeable aqueous zinc‐based batteries (AZBs) have been recently considered as desirable energy storage devices for renewable energy storage because of their high theoretical capacity, low cost, and high safety. Despite the inspiring achievements in this field, the energy density of AZBs is still far below expectation, which directly hinders their practical application as next‐generation secondary cells. To address this issue, previously, reseach efforts have been mainly dedicated to the improvement of capacity by designing different kinds of high‐capacity electrode candidates, especially the cathode materials. In recent years, elevation of the output voltage for energy density improvement has gained more and more attention. The main limitation of the relatively low output voltage of AZBs lies in the narrow electrochemically stable window of aqueous electrolytes, which results in limited choice of cathode materials with high potential. Herein, by summarizing recently reported work in this field, the strategies applied to high‐voltage AZB construction are classified into two categories, from the aspects of electrode and battery structure. Classic examples of each category are discussed in detail, and their respective advantages/defects are compared and commented on. Finally, further challenges are elaborated to provide more insights into this area.

“…Polyaniline (PANI), probably the most studied conducting polymer, is a promising cathode material for aqueous zinc batteries, 1–7 mainly due to its good electrical conductivity, high electrochemical reactivity/reversibility, and low cost. 8–22 Depending on the oxidation degree, three forms of PANI have been recognized: reduction state (leucoemeraldine), half oxidation state (emeraldine), and oxidation state (pernigraniline) (Scheme 1).…”

“…It is worth noting that ARBs may be divided into four categories according to the energy storage mechanisms of the electroactive materials: Systems with i) conventional ion insertion, ii) dual ion co-insertion, iii) conversion reaction, and iv) coordination reaction. [24,25] As expected, a considerable number of ARBs with low cost, high safety, and outstanding electrochemical performance have been developed. [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] As a result of the emergence of the Internet of Things and the rapid development in biomimetics and artificial intelligence, a new class of multifunctional energy-storage devices has emerged.…”

safe, environmentally friendly, and costefficient energy storage technologies. Since renewable and green energy sources such as solar, wind, and tide are available only intermittently, batteries are an exceptionally promising technology to store electricity generated from such sources for later use at the peak consumption times in large scale networks. [1][2][3][4] Commercial lithium-ion batteries (LIBs) with high energy density, cycle stability, and energy efficiency have dominated the energy storage field, and they provide a great convenience for our modern lives. [5,6] However, their further applications are hindered by safety concerns involving the use of harmful organic electrolytes and by the high cost of the appropriate electrode materials. [7,8] Lately, abundant sodium and potassium resources in nature have attracted much attention because of their similar chemical properties to lithium, where sodium-ion batteries and potassium-ion batteries have, thus, become promising alternatives for LIBs. [9][10][11][12] Although the issue of high cost can be solved using such novel battery materials, the usage of conventional organic electrolytes that are toxic and flammable still affects the safety of battery operation. Therefore, in recent years, large researchThe ORCID identification number(s) for the author(s) of this article can be found under
