“…[75] According to the difference of valent state, the ions intercalation can be normally divided into the monovalent and multivalent metal ions intercalation, while the practical intercalating effect of them seems to be more depending on their ionic radius. [19,95,153,[165][166][167][168][169][170] For multivalent metal ions, many types of ion have been successfully applied, such as Fe 2+ , Co 2+ , Ni 2+ , Mn 2+ , Zn 2+ , Mg 2+ , etc., while monovalent metal ions include the Li + , Na + , K + , and so on. [171][172][173] Take the most commonly used layered V 2 O 5 for example, although this material exhibits the ultrahigh theoretical Zn 2+ storage capacity, however, those inherent shortcomings of structural instability, low electrical conductivity, as well as the sluggish ions transport kinetics have greatly impeded its application in AZIBs.…”

“…[171][172][173] Take the most commonly used layered V 2 O 5 for example, although this material exhibits the ultrahigh theoretical Zn 2+ storage capacity, however, those inherent shortcomings of structural instability, low electrical conductivity, as well as the sluggish ions transport kinetics have greatly impeded its application in AZIBs. [168] To address those questions, Alfaruqi et al [175] employed the ions preintercalated strategy to realize the improvement of the electrochemical performance of V 2 O 5 cathode material. As shown in Figure 6a, the SEM, TEM, and corresponding energy dispersive spectrometer (EDS) elemental mapping images demonstrated that the metal ions (Fe 2+ , Co 2+ , Ni 2+ , Mn 2+ , and Zn 2+ ) have been homogeneously intercalated into the interlayer of V 2 O 5 , and without any obvious structural collapse.…”

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...

“…When H 2 O and Li + was intercalated into the interlayers of V−O, it could respectively expand and maintain the layered galleries of V 2 O 5 ‐based materials, thus facilitating the Zn 2+ diffusion, and stabilized the structure during cycling [18] . Similarly, hydrated pre‐intercalation of Al 3+ with small ion radius but high charge density can also expand the d‐spacing to lay a solid foundation for the rapid Zn 2+ diffusion kinetics [81] . Wide diffusion paths also enable the electrodes to maintain high capacity retention even with high mass load (∼15.7 mg cm −2 ), which is significantly important for the possible actual production [82] …”

Advantages concerns about abundant resources, low cost and high safety have promoted sodium‐ion batteries (SIBs) and aqueous zinc‐ion batteries (AZIBs) as the most promising candidates for next generation of low‐cost large‐scale energy storage. However, the state‐of‐the‐art cathode materials are far from meeting the commercial requirements. Considering the unique open framework, layered vanadium oxides have attracted wide attention due to the high energy density and power density, while they also face critical issues such as low stability and sluggish diffusion kinetics. The interlayer doping defects, as the most common method modulating layered materials, are believed to solve these problems which will be highlighted in this review. Firstly, the characteristics and current states of various vanadium oxides in SIBs and AZIBs are summarized. Then, the research efforts related to different types of interlayer doping defects, including ionic, molecular doping, etc., are discussed. Finally, it is pointed out that it is not enough to merely achieve satisfactory performances. Hence, some perspectives about the deep understanding and interrelationship are provided for the subsequent rational design of defective layered vanadium oxides for low‐cost energy storage systems.

“…Although Al cations possess small atomic radii, the strong electrostatic repulsion of V 5+ as well as the high valence state of Al produce a larger interlayer spacing of 13.4 Å. [ 40 ] Metal ion and water co‐intercalation is commonly performed in the design of PIB electrodes. Li and co‐workers investigated K x V 2 O 5 ·nH 2 O and 3D nanoporous Au current collectors‐integrated anodes for potassium ion batteries (Figure 5e–g).…”

With the constant focus on energy storage devices, layered materials are ideal electrodes for the new generation of highly efficient secondary ion batteries and supercapacitors due to their flexible 2D structures and high theoretical capacities. However, the small interlayer distances in layered electrode materials and the strong Columbic interactions between the working ions and host lattice anions cause slow ion diffusion. In addition, structural collapse during repeated ion insertion and extraction reduces the cycling lifetime. As such, interlayer engineering strategies are effective approaches to optimize ion transmission kinetics and structural integrity. In view of the latest research on the interlayer engineering of layered materials, this review will discuss useful strategies to improve electrode performance. The synthetic strategies, characterization techniques, and effects of interlayer‐engineered layered materials, including metal oxides, metal sulfides, carbonous materials, and MXenes, are discussed in detail. The future outlook and challenges for interlayer engineering are also presented, which may pave the way for the development of new layered materials.
