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 (hG) 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 hG strategy is powerful in enhancing overall electrochemical performance.

分层石墨烯的C等离子可幸存SnS束，以用于超稳定和高容量的钠离子存储

锡及其衍生物激发了高容量钠离子阳极材料的巨大进步。然而，在单个电极中保持较高的面积和体积容量并保持长期稳定性仍然是一项挑战。在此，开发了一种优雅且用途广泛的策略，以显着延长硫化锡纳米带电极的寿命和速率能力，同时保持较高的面积和体积容量。在这种策略中，原位成束的稳健的分层石墨烯（hG）通过快速（5分钟）碳等离子方法在硫化锡纳米带网络上均匀生长，其中可持续油为碳源，部分还原的Sn为催化剂。使用密度泛函理论计算系统地研究了Sn（111）表面上石墨烯CN（尺寸N在1至24之间）的成核作用。结果表明，这种化学键合的h G策略在增强整体电化学性能方面具有强大的作用。
