摘要 采用不同碳材料与升华硫复合得到不同正极材料,并加入添加剂以改善放电曲线。对所得材料进行X射线衍射(XRD)、算比表面积(BET)、扫描电子显微镜(SEM)、热重分析(TG)等物理性能表征,研究其电化学性能,探究不同碳材料、制备工艺及添加剂对复合材料性能的影响。 Different kinds of cathode materials were obtained by compounding different carbon materials with sublimed sulfur, and additives were mixed in the materials to improve discharge curves. The compounded materials were characterized by X-ray diffraction(XRD), brunauer-emmett-teller(BET), scanning electron microscopy(SEM) and thermogravimetry analysis(TG) to study the electrochemical characteristics, exploring the influence of different species of carbon materials, additives and preparation methods on the performances of compounded materials.
