“…In addition to Zn 2þ intercalation mechanism in Na 2 V 6 O 16 •3H 2 O, a simultaneous H þ and Zn 2þ intercalation was observed in NaV 3 O 8 •1.5H 2 O. [45] Some other types of layered vanadates such as Zn 3 [49] V 2 O 3, [50] VO 2, [51,52] and VS 2 [53] were also reported with Zn 2þ ion storage behaviors in aqueous Zn batteries.…”

Rechargeable mild aqueous zinc batteries have recently attracted tremendous interest for large‐scale grid storage due to their potentially highest energy density and safety, and lowest cost among available aqueous battery technologies. Herein, a variety of cathode materials, zinc anode structures, and electrolytes are briefly reviewed. A multi‐type of charge carriers such as Zn2+, H+, and anions can be reversibly stored in cathodes in rechargeable mild aqueous zinc batteries. The charge storage behavior in cathodes and strategies to address the reversibility and dendrite growth of zinc anodes are comprehensively summarized. Solutions to the remaining challenges such as long‐term stability and economy of cathodes and zinc anodes are discussed. This review also includes an analysis of mild aqueous zinc battery chemistry with reported cathode materials and anode materials. A perspective for the practical development of rechargeable mild aqueous zinc batteries regarding cathode design, zinc anode utilization, and cell configuration is also included to accelerate the commercialization of zinc batteries. In the future, rechargeable mild aqueous zinc batteries would be a visible energy storage solution for grid storage.

“…[ 221 ] Up to date, conductive carbon coating has attracted more research attention in energy storage and conversion fields when compare with conductive polymer coating. In the studies of AZIBs, many types of cathode materials modified by carbon coating have been reported, such as α‐MnO 2 @C, [ 222 ] δ‐MnO 2 @CAC, [ 223 ] MnO 2 @CC, [ 145 ] MnO x @CNF, [ 224 ] V 2 O 3 @C, [ 225 ] Mn 3 O 4 @N doped carbon matrix nanorods (Mn 3 O 4 @NC Nrs), [ 84 ] and so on. To deep understanding how does the carbon coating improve the electrochemical performance of cathodes, here, a typical case is given.…”

have also greatly aroused the positive exploration of alternative LIB technologies in recent years. [44] In contrast to the flammable organic electrolyte in LIBs, the aqueous one exhibits lower cost, higher safety, and especially the superior ionic conductivity, which is generally two orders of magnitude higher than that of the organic system. [9,10] All those unparalleled advantages would make the aqueous battery technologies to be the promising candidates in the future. [11] Rechargeable aqueous zinc-ion batteries (AZIBs), which is mainly composed of zinc metal anode, zinc salt-based aqueous electrolyte, and Zn 2+ host cathode, hold the great promise for energy storage applications in very recent years. [12,13] Compared with nonaqueous alkali-ion batteries, the use of cheap and high ambient stable zinc metal anode and inexpensive aqueous electrolyte with superior ionic conductivity (Figure 1a) would make such type of battery to be one of the most promising commercial candidates in the future market. [14-17] To date, extensive studies have been reported for AZIBs, and relating publications have dramatically increased especially in these two years, as shown in Figure 1b. However, the insufficient energy density seems to become the bottleneck that hinder their practical applications at current status. [4,5,18] Such issue could be ascribed to the narrow operating voltage of aqueous electrolyte, insufficient electrochemical performance of cathode materials, and Zn anode. [13,19,20] Besides, the influence of other components such as separator and collector also should be considered to some extent. [20,21] Among them, the studies of widening operating voltage of electrolyte and the optimization of other components only received less attention, which still remain at the early stage. [22,23] On the contrary, more attentions were paid to the electrochemical performance tuning of electrode materials. [24-26] Besides, considering the fixed operating voltage of Zn metal anode, the modification of cathode materials seems to provide more possibilities to effectively improve the energy density of AZIBs, owing to their rich material systems. [20,26,27] Under these considerations, the rational design of advanced cathodes is expected to be a preferential task to develop. Up to now, many types of materials have been exploited as cathode candidates and applied for AZIBs, however, those Rechargeable aqueous zinc-ion batteries (AZIBs) have attracted extensive attention and are considered to be promising energy storage devices, owing to their low cost, eco-friendliness, and high security. However, insufficient energy density has become the bottleneck for practical applications, which is greatly influenced by their cathodes and makes the exploration of high-performance cathodes still a great challenge. This review underscores the recent advances in the rational design of advanced cathodes for AZIBs. The review starts with a brief summary and evaluation of cathode material systems, as well as the introduction of proposed storage mechani...
