“…Some studies have successfully proved that β-MnO 2 has excellent zinc storage performance. [86][87][88][89] A previous study by Kang et al 90 revealed that massive β-MnO 2 delivered low electrochemical activity in ZIBs. In a subsequent work, Kang et al 91 achieved reversible insertion/extraction of Zn 2+ ions into/from β-MnO 2 with a porous framework.…”

“…In these structures, the basic structural unit MnO 6 octahedra is connected to each other by co‐angle/co‐edge, constructing chain, tunnel, layered structures with enough space accommodating foreign cations . Given this structural advantage, MnO 2 has been extensively investigated as favorable cathodes for batteries in the past several years, including Li‐ion batteries, Na‐ion batteries, K‐ion batteries, Mg‐ion batteries, and latest ZIB . Theoretically, MnO 2 can accommodate one Zn 2+ insertion per formula with a high theoretical capacity of approximately 616 mAh/g, in which the Mn 4+ is reduced to Mn 2+ .…”

Li‐ion batteries (LIBs) with excellent cycling stability and high‐energy densities have already occupied the commercial rechargeable battery market. Unfortunately, the high cost and intrinsic insecurity induced by organic electrolyte severely hinder their applications in large‐scale energy storage. In contrast, aqueous Zn‐ion batteries (ZIBs) are being developed as an ideal candidate because of their cheapness and high security. Benefiting from high operating voltage and acceptable specific capacity, recently, manganese‐based oxides with different various crystal structures have been extensively studied as cathode materials for aqueous ZIBs. This review presents research progress of manganese‐based cathodes in aqueous ZIBs, including various manganese‐based oxides and their zinc storage mechanisms. In addition, we also discuss some optimization strategies that aim at improving the electrochemical performance of manganese‐based cathodes, and the design of flexible aqueous ZIBs based on manganese‐based cathodes (MZIBs). Finally, this review summarizes some valuable research directions, which will promote the further development of aqueous MZIBs.

“…On the other hand, another commonly used MnO 2 materials were also studied. For example, Liu et al [270] fabricated the MnO 2 nanowire (Figure 17b) to construct a novel on-chip Langmuir-Blodgett nanowire (LBNW) micro device for directly probing Zn-ion batteries in real-time. For the first time, they revealed the conductance of MnO 2 LBNW monotonically increase/decrease upon the charge/discharge process.…”

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...
