VS4 with a high theoretical specific capacity is considered as a potential anode material for sodium-ion batteries. In this work, VS4 nanosheets was firstly synthesized through a simple solvothermal method using N-methyl pyrrolidone (NMP) as the solvent. The unique nanosheets structure is beneficial to the transmission of Na+/electrons and the wetting of electrolyte. Benefiting from the special structure, the prepared VS4 exhibits satisfactory sodium storage performance, especially the cycle stability at a high current density (534 mA h g-1 after 500 cycles at 1 A g-1) and excellent coulomb efficiency (about 100% since the second cycle). Most importantly, this work provides a feasible and simple method for preparing transition metal sulfides nanosheets, which can be used in energy storage devices.
