Hollow carbon materials have been extensively investigated as sulfur hosts for lithium‐sulfur batteries. Herein, we report a designed synthesis of nitrogen‐doped mesoporous hollow carbon spheres with tunable void spaces through an ethylenediamine‐assisted cooperative self‐assembly strategy between 3‐aminophenol/formaldehyde resin and silica. Nitrogen‐doped hollow mesoporous carbon spheres (NHMCS) with an optimised inside/outside radius ratio of 0.52 have induced improved electrochemical performances compared to other NHMCS, demonstrating a fine material design strategy for electrochemical energy storage systems with improved performance.

调制锂硫电池的氮掺杂空心中孔碳球的空隙空间

中空碳材料已被广泛研究为锂硫电池的硫主体。本文中,我们报告了一种通过3-氨基苯酚/甲醛树脂与二氧化硅之间的乙二胺辅助协同自组装策略设计的,具有可调空隙空间的氮掺杂介孔中空碳球的合成方法。与其他NHMCS相比,优化的内/外半径比为0.52的氮掺杂空心中孔碳球(NHMCS)诱导了改进的电化学性能,证明了具有改进性能的电化学储能系统的精细材料设计策略。
