Nitrogen and sulfur co-doped porous carbon spheres (NS-PCSs) were prepared using L-cysteine to control the structure and functionalization during the hydrothermal reaction of glucose and the subsequent activation process. As the sulfur hosts in Li-S batteries, NS-PCSs combine strong physical confinement and surface chemical interaction to improve the affinity of polysulfides to the carbon matrix.
采用L-半胱氨酸制备了氮硫共掺杂多孔碳球（NS-PCSs），以在葡萄糖水热反应及后续活化过程中控制结构和功能化。作为锂硫电池中的硫载体，NS-PCSs结合了强大的物理限制和表面化学相互作用，以提高多硫化物与碳基体的亲和力。
