用扫描电子显微镜和X射线衍射仪研究了以明胶为粘结剂的多孔硫阴极的结构变化。原始硫磺阴极呈现出硫、碳和气孔的均匀分布。在放电过程中，气孔和元素硫逐渐消失。但充电后，这些变化发生了逆转，元素硫发生了重整，从而提高了锂硫电池的电化学性能。
The structural change of the porous sulfur cathode using gelatin as a binder was studied by means of scanning electron microscopy (SEM) and X-ray diffractometry (XRD). The original sulfur cathode exhibited a homogenous distribution of sulfur, carbon and pores. During the discharge process, the pores and elemental sulfur disappeared gradually. However, those changes were reversed and elemental sulfur was reformed after the charge process, which improved the electrochemical performance of lithium–sulfur batteries.
