摘要: Porous hollow carbon spheres with different tailored pore structures have been designed as conducting frameworks for lithium–sulfur battery cathode materials that exhibit stable cycling capacity. By deliberately creating shell porosity and utilizing the interior void volume of the carbon spheres, sufficient space for sulfur storage as well as electrolyte pathways is guaranteed. The effect of different approaches to develop shell porosity is examined and compared in this study. The most highly optimized sulfur–porous carbon nanosphere …
