Abstract In this work, an ultrathin sulfur-doped Graphene-like carbon (S/C) layer wrapped Ni3S2/Ni composite (Ni3S2/Ni@S/C) is simply fabricated by in situ growth of an ultrathin sulfur-doped Graphene-like carbon layer on the Ni3S2/Ni surface, and used as an anode material for sodium ion batteries, which shows a high specific capacity (318.2 mA h g−1 at 100 mA g−1 after the 120 cycles) and excellent cyclic stability (212.7 mA h g−1 at 1000 mA g−1 after 250 cycles with a corresponding cycles capacity retention of 97.6%).

Ni3S2/Ni@S/C复合材料：合成简便，高性能作为钠离子电池负极

摘要 在这项工作中，超薄硫掺杂类石墨烯碳 (S/C) 层包裹 Ni3S2/Ni 复合材料 (Ni3S2/Ni@S/C) 是通过原位生长超薄硫掺杂类石墨烯而简单制备的。 Ni3S2/Ni 表面的碳层，用作钠离子电池的负极材料，显示出高比容量（120 次循环后 100 mA g-1 时为 318.2 mA hg-1）和优异的循环稳定性（212.7 mA hg-1 at 1000 mA g-1 250 次循环后，相应的循环容量保持率为 97.6%）。
