A hierarchical composite of rose‐like VS2@S/N‐doped carbon with expanded (001) planes is synthesized via a facile one‐pot solvothermal route. Benefiting from outstanding conductivity, improved Li+ diffusion kinetics, and hierarchical structure, the VS2@SNC electrode exhibits an outstanding rate capability and a remarkable long‐term cycling stability with a capacity of 684.5 mA h g−1 after 600 cycles at 8 A g−1. Abstract In the present work, a hierarchical composite of rose‐like VS2@S/N‐doped carbon (VS2@SNC) with expanded (001) planes is successfully fabricated through a facile synthetic route. Notably, the d‐spacing of (001) planes is expanded to 0.92 nm, which is proved to dramatically reduce the energy barrier for Li+ diffusion in the composite of VS2@SNC by density functional theory calculation. On the other hand, the S/N‐doped carbon in the composite greatly promotes the electrical conductivity and enhances the structural stability. In addition, the hierarchical structure of VS2@SNC facilitates rapid electrolyte diffusion and increases the contact area between the electrode and electrolyte simultaneously. Benefiting from the merits mentioned above, the VS2@SNC electrode exhibits excellent electrochemical properties, such as a large reversible capacity of 971.6 mA h g−1 at 0.2 A g−1, an extremely high rate capability of 772.1 mA h g−1 at 10 A g−1, and a remarkable cycling stability up to 600 cycles at 8 A g−1 with a capacity of 684.5 mA h g−1, making it a promising candidate as an anode material for lithium‐ion batteries.
