摘要
Abstract Rechargeable metal‐ion batteries (RMIBs), as one of the most viable technologies for electric vehicles (EVs) and large‐scale energy storage (EES), have received extensive research attention for a long time. Electrode materials play a decisive role on capacity, energy, and power density, which directly affect the practical applications of RMIBs in EVs and EES. As an electrode material, layered metallic vanadium disulfide (VS 2 ) has theoretically and experimentally produced inspiring results because of its synthetic characteristics of continuously adjustable V valence, large interlayer spacing, weak interlayer interactions, and high surface activity. Herein, the synthetic strategies, theoretical metal‐ion storage sites, diffusion kinetics, and experimental electrochemical reaction mechanisms of VS 2 for RMIBs are systematically introduced. Emphatically, the critical issues that affect the metal‐ion storage properties of the VS 2 electrode and three major enhancement strategies, namely, optimizing the electrolyte and cutoff voltage, constructing a space‐confined structure, and controlling the crystal structure are summarized, with the aim of promoting the development of transition‐metal dichalcogenides. Finally, the challenges and opportunities for the future development of VS 2 in the energy‐storage field are presented. It is hoped that this review can attract attention from researchers for investigations into emerging layered metallic VS 2 and provide insights toward the design of an excellent VS 2 electrode material for next‐generation, high‐performance RMIBs.
