Tin and its derivatives have provoked tremendous progress of high‐capacity sodium‐ion anode materials. However, achieving high areal and volumetric capability with maintained long‐term stability in a single electrode remains challenging. Here, an elegant and versatile strategy is developed to significantly extend the lifespan and rate capability of tin sulfide nanobelt electrodes while maintaining high areal and volumetric capacities. In this strategy, in situ bundles of robust hierarchical graphene ( h G) are grown uniformly on tin sulfide nanobelt networks through a rapid (5 min) carbon‐plasma method with sustainable oil as the carbon source and the partially reduced Sn as the catalyst. The nucleation of graphene, CN (with size N ranging from 1 to 24), on the Sn(111) surface is systematically explored using density functional theory calculations. It is demonstrated that this chemical‐bonded h G strategy is powerful in enhancing overall electrochemical performance.
