“…Pillaring of layer structured vanadium-and MnO 2 -based materials with metal ions, and structural water increase the interlayer spacing and favor the facile insertion/extraction of charge carrier. [71,112,[154][155][156][157][158][159][160][161]…”

“…into layer/tunnel structured vanadium-based oxides also improves the performance of ZIB due to the phenomenal increase in the interlayer spacing. [155,156,158,[161][162][163][164][165] For instance, the interlayer spacing (d 001 = 11.45 Å) of Cu 0.1 V 2 O 5 • 0.08 H 2 O is significantly higher than the parent V 2 O 5 (5.77 Å) (Figure 5a). Such a large increase in the interlayer spacing enhances the ion diffusion, and improves the structural stability of the material during repeated potential cycling.…”

The growing demand for the renewable energy storage technologies stimulated the quest for efficient energy storage devices. In recent years, the rechargeable aqueous zinc-based battery technologies are emerging as a compelling alternative to the lithium-based batteries owing to safety, eco-friendliness, and cost-effectiveness. Among the zinc-based energy devices, rechargeable zinc-ion batteries (ZIBs) are drawing considerable attention. However, they are plagued with several issues, including cathode dissolution, dendrite formation, etc.. Despite several efforts in the recent past, ZIBs are still in their infant stages and have yet to reach the stage of large-scale production. Finding stable Zn 2 + intercalation cathode material with high operating voltage and long cycling stability as well as dendrite-free Zn anode is the main challenge in the develop-ment of efficient zinc-ion storage devices. This Review discusses the various strategies, in terms of the engineering of cathode, anode and electrolyte, adopted for improving the charge storage performance of ZIBs and highlights the recent ZIB technological innovations. A brief account on the history of zinc-based devices and various cathode materials tested for ZIB fabrication in the last five years are also included. The main focus of this Review is to provide a detailed account on the rational engineering of the electrodes, electrolytes, and separators for improving the charge storage performance with a future perspective to achieving high energy density and long cycling stability and large-scale production for practical application.

“…In fact, transition metal ions can achieve more attractive functions according to the adjustable d orbital electrons, such as improving electronic conductivity as mentioned above. According to the formula (3), compared with the main group element Mg−O bond with ∼32% covalent property, the covalence of Cu−O bond is ∼55% [90] . Therefore, the partially unfilled 3 d orbital of pre‐intercalated Cu 2+ cations can realize high electron sharing and feasible electron transfer, reducing the impedance and accelerating the redox reaction (Figure 7b) [91] .…”

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.

“…[ 28 ] The authors also investigated the pre‐intercalation effects of inserting Cu(II) into hydrated vanadium pentoxide (VOH) in comparison to Mg‐intercalated VOH. [ 29 ] Although the ionic radius of Cu (II) is similar to that of Mg(II) (87 pm for Cu and 86 pm for Mg), the interlayer distances that they produce are different. The larger interlayer distance generated by Cu(II) insertion (≈13.2 Å), compared to that of Mg(II) (≈11.2 Å), can be ascribed to the difference in electronegativity between the two cations.…”

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.
