“…In recent years, layered transition-metal sulfides have attracted much attention due to their weak van der Waals forces and tunable interlayer distances for enhancing Mg 2+ transportation, such as MoS 2 , WS 2 , VS 4 , and TiS 2 . Among them, vanadium tetrasulfide (VS 4 ) has the chainlike crystal structure with a large interchain distance (0.58 nm), which could be regarded as a potential cathode material of MIBs.…”

The development of cathode materials with a high electric conductivity and a low polarization effect is crucial for enhancing the electrochemical properties of magnesium-ion batteries (MIBs). Herein, Mo doping and nitrogen-doped tubular graphene (N-TG) introduction are carried out for decorating VS4 (Mo-VS4/N-TG) via the one-step hydrothermal method as a freestanding cathode for MIBs. The results of characterizations and density functional theory (DFT) reveal that rich sulfur vacancies are induced by Mo doping, and N-TG as a high conductive skeleton material serves to disperse the active material and forms a tight connection, all of which collectively improved the electrical conductivity of electrode and increased the adsorption energy of Mg2+ (−6.341 eV). Furthermore, the fast reaction kinetics is also confirmed by the galvanostatic intermittent titration technique (GITT) and the pesudocapacitance-like contribution analysis. Benefiting from the synergistic effect of electrical conductivity enhancement and rich vacancy introduction, Mo-VS4/N-TG delivers a steady Mg2+ storage specific capacity of about 140 mAh g–1 at 50 mA g–1, outstanding cycle stability (80.6% capacity retention ratio after 1200 cycles under 500 mA g–1), and excellent rate capability (specific capacity reaches 77.1 mAh g–1 when the current density reaches 500 mA g–1). In addition, the reversible reaction process, intercalation mechanism, and structural stability during the Mg2+ insertion/extraction process are confirmed by a series of ex situ characterizations. This research provides a sustainable and scalable strategy to spur the development of MIBs.

The increased demand for energy has prompted users to seek alternative energy storage devices. Post‐Li‐ion battery chemistries have been considered potential contenders for the development of next‐generation battery technologies. The high specific capacity (≈1675 mAh g−1) and high natural abundance (≈953 ppm) of sulfur provide opportunities to meet the rigorous requirements of the market's demands, such as high energy density and low cost. When combined with a high capacity metal anode (e.g., Na ≈ 1165 mAh g−1, Mg ≈ 2205 mAh g−1, and Al ≈2980 mAh g−1), it leads to high energy density that can outperform the existing battery technologies, including high‐energy Li‐ion batteries. Despite the unique attributes of the sulfur‐based battery system, it remains in infancy owing to the complex reaction chemistry of sulfur cathode, and the level of complexity increases with an increase in valency of metal ions. This review summarizes the unique aspects of a sulfur cathode essential to stabilizing sulfur cathode‐based high‐energy rechargeable batteries. Furthermore, deeper insight into the electrochemical performance of various metal–sulfur‐based systems has been provided. This review may pave the path for the researchers to accelerate the development of sulfur cathode for post‐Li‐ion batteries.
