“…After cycling, the material changes from crystalline to amorphous, and the regular lattice fringes of the material are hardly invisible in the HRTEM image. This process has been widely observed in cathodes of battery systems. ,, As shown in Figure c, the lattice fringe with 0.218 nm d-spacing can be observed, which belongs to the (111) plane of metal V. It can be explained that with the further intercalation process of Al 3+ ions, Al n VS 4 transforms into Al 2 S 3 and V, corresponding to the reduction reaction of the V element at the discharge process. The results of TEM are consistent with the results of XPS, which indicate that the conversion reaction of VS 4 can occur during charge and discharge processes.…”

Rechargeable aluminum batteries (RABs) are gaining widespread attention for large-scale energy storage applications as a result of their high energy densities, high security, and abundance. The key to sustain the progress of RABs lies in the quest for the proper cathode materials with prominent capacity and reversible cycle life. Herein, we propose a tremella-like VS 4 as a cathode material aiming to tackle this problem. Obtained from a morphology modification process, VS 4 with a unique nanosheet structure provides sufficient active sites for intercalation and conversion reactions, shortens the transport paths for charge carrier ions, and facilitates the infiltration process for electrolyte. The RAB with the VS 4 cathode exhibits excellent electrochemical performance, including outstanding specific capacity (407.9 mAh g −1 ) and stable cycling performance (∼300 cycles at a high current density). The energy storage mechanism has been comprehensively investigated and is confirmed to be a combination of the intercalation/ deintercalation of Al 3+ and AlCl 4 − ions and conversion reaction by various techniques and DFT calculation. Our study not only provides a peculiar and simple strategy for the rational design of metal sulfide cathode materials with high capacity and long-term stability but also proposes a specific energy storage mechanism that guides the development of cathode materials of RABs in the future.

“…Due to the aligned interlayer diffusion channels formed by (002) crystal planes vertical to the surface, the migration path and resistance of sodium ions along the surface of the 2D material become smaller, which is more beneficial to enabling the rapid diffusion of Na + . [21,22] The energy-dispersive X-ray spectroscopy (EDS) mapping of vertical-V 5 S 8 in Figure 2m,n shows that the O, C, S, and V elements are uniformly distributed, but the Mo element is mainly distributed in the interior of the nanorods (MoO 3 template). In the TEM images of vertical-V 5 S 8 materials (Figure 2m), the content of V 5 S 8 nanosheets is much smaller than that observed in SEM images (Figure 2j).…”

Sodium‐ion batteries (SIBs) have inspired the potential for widespread use in energy storage owing to the advantages of abundant resources and low cost. Benefiting from the layered structure, 2D‐layered materials enable fast interlayer transport of sodium ions and thus are considered promising candidates as anodes for SIBs. Herein, a strategy of adjusting crystal orientation is proposed via a solvothermal method to improve sodium‐ion transport at the edge of the interlayers in 2D‐layered materials. By introducing surfactants and templates, the 2D‐layered V5S8 nanosheets are controlled to align the interlayer diffusion channels vertically to the surface, which promotes the fast transport of Na+ at the edge of the interlayers as revealed by experimental methods and ab initio calculations. Benefiting from the aligned crystal orientation and rGO coating, the vertical‐V5S8@rGO hybrid delivers a high initial discharge capacity of 350.6 mAh g−1 at a high current density of 15 A g−1. This work provides a strategy for the structural design of 2D‐layered anode materials by adjusting crystal orientation, which demonstrates the promise for applications in fast‐charging alkaline‐ion batteries.

VS 4 , also known as patronite, is a widely studied nanostructured material due to its fascinating high theoretical capacity. VS 4 has been getting much attention in supercapacitor as well as battery applications due to its parallel one-dimensional chain-like structure with an interchain spacing of 5.83 Å, which helps to provide space for accommodating the insertion/extraction of ions. There have been a number of scientific reports published on VS 4 and VS 4 -based nanocomposites for energy storage applications recently. In this aspect, here we summarize the charge storage properties of VS 4 and its nanocomposites including rGO, CNTs, MXenes, metal chalcogenides, and other carbonbased composites for supercapacitor applications. Moreover, challenges and future perspectives of VS 4 -based electrode materials are included in the conclusion.
