Recently, sodium ion batteries (SIBs) have exhibited great application potential in the area of renewable energy storage. However, developing anodes for SIBs with excellent cycling stability and high capacity is a great challenge. In recent years, VS2 attracts more attention due to its high specific capacity. In this work, three-dimensional (3D) rose-like VS2 self-assembled from nanosheet was prepared via a solvothermal method using N-methylpyrrolidone as the solvent. The special 3D structure facilitates electron/Na+ transport and can relieve the volume change during Na+ insertion/extraction. Benefitting from the 3D self-assembled structure, VS2 exhibits outstanding cycling stability at high current density. Even when tested at 5 A g(-1), the 3D VS2 electrode can maintain a high capacity of 565 mA h g(-1) after 350 cycles. Through pseudo-capacitance contribution calculation, we speculate that the high capacitance contribution confers the superior high rate performance to the VS2. This work sheds a new light on the design and preparation 3D VS2, which can be utilized as an excellent anode for SIBs.
