In this study, we fabricated a cathode with lower amounts of additive materials and higher amounts of active materials than those of a conventional cathode. A thermal battery was fabricated using FeS treated foam as the cathode frame, and its feasibility was verified. X-ray diffraction, transmission electron microscopy, and scanning electron microscopy were used to analyze the effects of thermal sulfidation temperature (400 and 500°C) on the structure and surface morphology of the FeS foam. The optimal temperature for the fabrication of the FeS treated foam was determined to be 500°C. The FeS treated foam reduced the interfacial resistance and improved the mechanical strength of the cathode. The discharge capacity of the thermal battery using the FeS treated foam was about 1.3 times higher than that of a thermal battery using pure Fe metal foam.
在本研究中，我们制备了一种添加剂材料含量低于传统阴极、活性材料含量高于传统阴极的阴极。使用经硫化铁处理的泡沫作为阴极框架制造了一种热电池，并验证了其可行性。利用X射线衍射、透射电子显微镜和扫描电子显微镜分析了热硫化温度（400和500°C）对硫化铁泡沫结构和表面形态的影响。确定制备经硫化铁处理的泡沫的最佳温度为500°C。经硫化铁处理的泡沫降低了界面电阻，提高了阴极的机械强度。使用经硫化铁处理的泡沫的热电池的放电容量比使用纯铁金属泡沫的热电池高约1.3倍。
