A severe shuttle effect and a poor sulfur utilization rate impede the application of Li–S batteries, and the rational design of sulfur host can alleviate these problems. Herein, we synthesized MoS2-modified three-dimensional (3D) porous carbon nanofibers (MoS2@CNF) as a sulfur host. The porous structure can offer channels for the transport of Li+ while accommodating more active materials. The doped MoS2 has strong chemisorption and electrocatalytic synergistic effect on polysulfide, which can accelerate the conversion of polysulfide. Consequently, these structural and chemical advantages allow S@MoS2@CNF cathode to achieve excellent electrochemical performance.

静电纺MoS 2装饰的多孔碳纳米纤维,用于高性能锂硫电池
严重的穿梭效应和较差的硫利用率阻碍了Li-S电池的应用,合理设计硫主体可以缓解这些问题。在这里,我们合成了MoS 2改性的三维(3D)多孔碳纳米纤维(MoS 2 @CNF)作为硫主体。多孔结构可提供用于输送Li +的通道,同时容纳更多的活性物质。掺杂的MoS 2对多硫化物具有很强的化学吸附作用和电催化协同作用,可以促进多硫化物的转化。因此,这些结构和化学上的优势使S @ MoS 2 @CNF阴极能够实现出色的电化学性能。
