Fig. 1 compares the X-ray diffraction (XRD) patterns of the pure sulfur, sulfur–carbon composite, and carbon black. The Super P carbon black, showing no sharp crystalline peaks, has amorphous structure. The pure sulfur and sulfur–carbon composite exhibit peaks perfectly matching with those of pure orthorhombic sulfur (JCPDS 00-008-0247). The sulfur–carbon composite shows much higher peak intensities than the pure sulfur as the dispersed nanoparticles of carbon black act as numerous deposition sites for elemental sulfur, leading to a favorable precipitation environment. This in situ sulfur deposition route thus provides an efficient means to produce high-purity sulfur composites. The microstructure of the carbon black, pure sulfur, and sulfur–carbon composite is shown in Fig. 2. The particle size of spherical carbon black is less than 100 nm. The pure sulfur contains glue-like particles with a diameter of few microns. Fig. 2(c) presents the structure of the sulfur–carbon composite in which sulfur particles are uniformly distributed throughout the network structure formed by carbon black. Carbon black partially embeds in the sulfur, and the remainder wraps around the matrix sulfur as a protective layer. This network structure confirms close contact between the conductive carbon and sulfur, providing not only excellent electron pathways for the insulating sulfur but also many adsorbent points to avoid the loss of the soluble polysulfides into the electrolyte. The TEM images in Fig. 3(a) and (b) show that the carbon black nanoparticles in the sulfur–carbon composite are chain-like, which effectively enhances the conductivity of the composite material [13]. The elemental analysis of the sulfur–carbon composite carried out by EDS is shown in Fig. 3(c), demonstrating the existence of both sulfur and carbon. |

Fig. 1 compares the X-ray diffraction (XRD) patterns of the pure sulfur, sulfur–carbon composite, and carbon black. 图1 对纯硫，碳硫复合物和炭黑的XRD图进行对比。 The Super P carbon black, showing no sharp crystalline peaks, has amorphous structure. Super P特密超导电炭黑并没有出现明显的结晶峰，说明其结构不规则。 The pure sulfur and sulfur–carbon composite exhibit peaks perfectly matching with those of pure orthorhombic sulfur (JCPDS 00-008-0247). 纯硫和碳硫复合物出现了与纯斜方晶系的硫相符的峰。 The sulfur–carbon composite shows much higher peak intensities than the pure sulfur as the dispersed nanoparticles of carbon black act as numerous deposition sites for elemental sulfur, leading to a favorable precipitation environment. 由于炭黑中分散的纳米颗粒为硫元素提供了大量的沉积场所，构成了一个良好的沉积环境。碳硫复合物的峰比纯硫的峰值强度更高。 This in situ sulfur deposition route thus provides an efficient means to produce high-purity sulfur composites. 因此硫的这种就地沉积方式为生产高纯度复合硫提供了一种很有效的方法。 The microstructure of the carbon black, pure sulfur, and sulfur–carbon composite is shown in Fig. 2. 炭黑，纯硫和碳硫复合物的微观结构如图2所示。 The particle size of spherical carbon black is less than 100 nm. 球形炭黑的颗粒大小不足100纳米。 The pure sulfur contains glue-like particles with a diameter of few microns. 纯硫中含有直径为几微米的胶状颗粒。 Fig. 2(c) presents the structure of the sulfur–carbon composite in which sulfur particles are uniformly distributed throughout the network structure formed by carbon black. 碳硫复合物的结构如图2（c）所示，硫颗粒均匀分布在炭黑的网状结构中。 Carbon black partially embeds in the sulfur, and the remainder wraps around the matrix sulfur as a protective layer. 部分炭黑嵌在硫中，其余的包围在硫矩阵外部作为保护层。 This network structure confirms close contact between the conductive carbon and sulfur, providing not only excellent electron pathways for the insulating sulfur but also many adsorbent points to avoid the loss of the soluble polysulfides into the electrolyte. 导电碳和硫之间由这种网状结构紧密连接，不仅为绝缘硫提供了良好的电子通路，并且提供了大量吸附点以抑制电解液中可溶硫聚物的流失。 The TEM images in Fig. 3(a) and (b) show that the carbon black nanoparticles in the sulfur–carbon composite are chain-like, which effectively enhances the conductivity of the composite material [13]. 从图3（a）和（b）的TEM图中可以看出，碳硫复合物中的炭黑纳米颗粒呈链状，利于有效的加强复合材料的导电性。 The elemental analysis of the sulfur–carbon composite carried out by EDS is shown in Fig. 3(c), demonstrating the existence of both sulfur and carbon. 图3（c）是通过EDS对碳硫复合物进行了元素分析，从图中可以看出硫和碳元素确实存在。 仅供参考…… |
