| 摘 要： | 本工作基于工业炼油产品沥青，开发了一种无金属、氮和硫共掺杂多孔碳纳米片（NSPC）的合成方法。获得的多孔碳纳米片具有高比表面积（339 m2·g-1）和优异的固硫能力。同时，高含量氮、硫共掺杂可以有效增强碳材料的导电性，同时促进多硫化物的高效催化转化。通过熔融法固硫后，制备得到的NSPC/S电极具有较高的比容量和优异的循环稳定性（在0.6C电流密度下，200次循环后容量为762 mAh·g-1），实现了高含量氮和硫共掺杂的二维多孔碳材料的快速批量生产并用于高性能锂硫电池正极材料。

| Abstract: | In this work, based on the industrial refinery product of pitch, we have developed a simple method for the production of metal-free, nitrogen, and sulfur co-doping porous carbon nanosheets (NSPC). The obtained NSPC exhibited a high specific surface area (339 m2·g-1) and puissant adsorbability for sulfur fixation. At the same time, the co-doping of N and S can effectively improve the electrical conductivity of carbon nanomaterials, and further improve the adsorption and conversion reaction of lithium polysulfides (LIPSs). The NSPC/S electrode delivered superior cycling performance (762 mAh·g-1 at 0.6C after 200 cycles). This work represents a rapid and massive production of two-dimensional porous carbon materials with high content of N and S as the cathode for advanced lithium-sulfur batteries. |
