以工业纳米SnO2为原料，采用静电纺丝法制备SnO2/C纳米纤维膜(SnO2/C NFM)，再经高温炭化处理，采用低温硫化法制备了SnO2/C纳米纤维膜(SnS/C NFM)。该方法不仅在高温下形成了高导电性、稳定的碳纤维骨架，而且避免了锡源的损失。自立式SnS/C NFM在不添加任何导电剂和粘结剂的情况下，作为钠离子电池(SIB)的负极具有优异的电化学性能。此外，与SnO2/C NFM和纳米SnO2相比，它的性能要好得多。经200 mA充放电−1循环200次后，可提供324 mA充放电−1的高容量(容量保持率高达84.8%)，并表现出良好的倍率性能。这种优异的电化学性能可以归因于3D导电网络的互连提高了SnS的导电性，并有效地抑制了SnS颗粒在循环过程中的聚集。因此，自立式SnS/C NFM被认为是很有前途的钠离子电池负极材料。
SnS/C nanofibers membrane (SnS/C NFM) has been synthesized by low-temperature vulcanization from SnO2/C nanofiber membrane (SnO2/C NFM), which is obtained via electrospinning using commercial nano SnO2as raw material followed by high-temperature carbonization. This method not only forms the high conductivity and stable carbon fiber skeleton in high temperature but also avoids the losing of tin source. The self-standing SnS/C NFM shows outstanding electrochemical properties as anode for sodium-ion batteries (SIBs) without adding any conductive agent and binder. Additionally, it exhibits much better performance compared to SnO2/C NFM and nano SnO2particles. After 200 cycles at 200 mA g−1, it can provide high capacity of 324 mA h g−1(up to 84.8% capacity retention rate), and also display a good rate performance. Such superb electrochemical performance can be attributed to the interconnection of the 3D conductive network to enhance the electrical conductivity of SnS, and effectively suppress the aggregation of SnS particles during the cycling process. Therefore, the self-standing SnS/C NFM is considered as promise anode materials for sodium-ion batteries.
