| 摘要: 通过硬模板法设计、制备了一种具有径向内排列骨架的内放射状中空TiN纳米颗粒(IRHTiNs)，并将其与硫(S)复合制备锂硫电池(LSB)正极。随后采用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线光电子能谱(XPS)和热重分析(TGA)表征了IRHTiNs及IRHTiNs/S复合正极的结构及成分。在电化学测试中，与C正极相比，以IRHTiNs为正极的LSB表现出了1 250mAh·g-1的高初始比容量，LSB的容量衰减速度明显降低，电池性能显著提升。 |

| Abstract: The inward radially hollow structure TiN particles (IRHTiNs) was designed and synthesized by using the hard-template method and combined with sulfur (S) to prepare lithium-sulfur batteries (LSB) cathodes. Subsequently, the structure and composition of IRHTiNs and IRHTiNs/S composite cathodes were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA). In the electrochemical test process, compared with the C cathodes, LSB using the IRHTiNs cathodes exhibited a high original specific capacity of 1 256 mAh·g-1, the capacity fading rate was significantly reduced, and the LSB performance was significantly improved. |
