Beschreibung
Zusammenfassung:The invention discloses a novel positive electrode active material for a positive electrode of a lithium-sulfur battery. The positive electrode active material of the present invention comprises: a) particles A comprising a first porous carbon material that is at least partially crystalline and catalyst particles deposited on the first porous carbon material; and b) particles B comprising a second porous carbon material that is at least partially crystalline and sulfur supported in the second porous carbon material, in which particles A and particles B have different morphologies. 本发明公开了一种用于锂硫电池正极中的新型正极活性材料。本发明的正极活性材料包含:a)粒子A,所述粒子A包含至少部分为结晶的第一多孔碳材料和沉积在第一多孔碳材料上的催化剂粒子;以及b)粒子B,所述粒子B包含至少部分为结晶的第二多孔碳材料和负载在第二多孔碳材料中的硫,其中,粒子A和粒子B具有不同的形态。
