“…The neighboring chains in VS 4 are held by weak Van der Waals forces, creating interchain gaps that can accommodate Mg 2+ ions. [86,87] The strategy of interchain expansion can be adopted to improve ion migration kinetics. Other 1D chain-like-structured compounds, such as TiS 3 and MoS 3 have also been explored as magnesium battery cathodes with promising electrochemical performance.…”

“…[13] Meanwhile, morphological control was demonstrated for VS 4 through manipulation of the growth kinetics by changing the concentration of the vanadium precursor. [86] An optimal vanadium precursor concentration was deemed necessary for the formation of robust nanosheet-laden architectures. Hierarchical nanosheet assemblies can also be prepared via microwave-assisted synthesis, which makes use of microwave reactors for fast heating of reaction mixtures.…”

“…Although a significant drop in reversible capacity was observed when the temperature was lowered (≈80 mAh g −1 at room temperature vs 170 mAh g −1 at 60 °C), it is still far better than micrometer-sized TiS 2 , which exhibited extremely poor electrochemical performance at room temperature. These results showed that obtaining a reversible reaction of Mg cathode is far difficult compared to that of Li cathode and hence nanosizing of cathode materials [12,27,29,31,36,39,42,43,[45][46][47][48]50,68,70,[86][87][88]90,[92][93][94][95][96][97][98].…”

“…A number of recent studies have focused on exploring nanostructured cathode materials with electrochemical behaviors that are primarily controlled by the capacitive effect. Examples of such materials are the VS 4 nanosheets, NiCo 2 Se 4 hierarchical assemblies, and a-MoS 3 @CNT composite nanowires [29,47,48,86,92] (Figure 8). In these cathode materials, the Mg 2+ storage mechanism largely relies on the capacitive process, in which the Faradaic process occurs via reversible redox reactions at the surface or near-surface of these pseudocapacitive cathode materials.…”

Rechargeable magnesium batteries (RMBs) are regarded as promising candidates for beyond‐lithium‐ion batteries owing to their high energy density. Moreover, as Mg metal is earth‐abundant and has low propensity for dendritic growth, RMBs have the advantages of being more affordable and safer than the currently used lithium‐ion batteries. However, the commercial viability of RMBs has been negatively impacted by slow diffusion kinetics in most cathode materials due to the high charge density and strongly polarizing nature of the Mg2+ ion. Nanostructuring of potential cathode materials such as metal chalcogenides offers an effective means of addressing these challenges by providing larger surface area and shorter migration routes. In this article, a review of recent research on the design of metal chalcogenide nanostructures for RMBs’ cathode materials is provided. The different types and structures of metal chalcogenide cathodes are discussed, and the synthetic strategies through which nanostructuring of these materials can be achieved are described. An organized summary of their electrochemical performance is also presented, along with an analysis of the current challenges and future directions. Although particular focus is placed on RMBs, many of the nanostructuring concepts that are discussed here can be carried forward to other next‐generation energy storage systems.

“…[211,212] Meng et al also investigated the morphology influence on the electrochemical performance of VS 4 . [213] Three controllable morphologies (solid sphere, flower-like microsphere and ultrathin nanosheets surrounded solid sphere) are obtained through the simple hydrothermal method. Among the three samples, the flower-like microsphere VS 4 has great quantity of interspace between nanosheets, higher surface area and active sites.…”

Rechargeable magnesium batteries (RMBs) have been regarded as one of the promising electrochemical energy storage systems to complement Li‐ion batteries owing to the low‐cost and high safety characteristics. However, the various challenges including the sluggish solid‐state diffusion of highly polarizing Mg2+ ions in hosts, and the formation of blocking layers on Mg metal surface have seriously impeded the development of high‐performance RMBs. In order to solve these problems toward practical applications of RMBs, a tremendous amount of work on electrodes and electrolytes has been conducted in the last few decades. Creative optimization strategies including the modification of cathodes and anodes such as shielding the charges of divalent Mg2+, expanding the layers of host materials, and optimizing the interface of electrode–electrolyte are raised to promote the technology. In this review, the detailed description of innovative approaches, representative examples, and facing challenges for developing high‐performance electrodes are presented. Based on the review of these strategies, guidelines are provided for future research directions on improving the overall battery performance, especially on the electrodes.

Sodium‐ion batteries (SIBs) have become an auspicious candidate for large‐scale energy storage by cause of low cost, natural abundance, and similar working principle with lithium‐ion batteries (LIBs). At present, there is an urgent need to explore superior anode materials with rapid and stable sodiation/desodiation. Herein, 3D self‐assembled VS4 curly nanosheets hierarchitectures (VS4‐CN‐Hs) are developed for SIB anodes, where VS4 possesses a large theoretical sodium storage capacity, and the building block of nanosheets has large exposed surface area to the electrolyte as well as the constructed hierarchitectures can provide abundant buffer space to alleviate the volume expansion. As a result, VS4‐CN‐Hs anode possesses excellent electrochemical performance under a wide voltage window of 0.01–3.0 V, such as high reversible capacity of 863 mA h g−1 at 0.1 A g−1, marvelous rate feature (444 mA h g−1 at 10 A g−1), and extralong cycle stability (386 mA h g−1 after 1000 times at 5 A g−1).
