| 图27 常规PP隔膜（a）和含CGF层的Janus隔膜（b）示意图。没有CGF层的隔膜，飞梭回来的LiPSs堆积在隔膜/正极界面并形成一个固态、没有活性、绝缘的钝化层。有CGF层的隔膜，LiPSs被还原并沉积在导电骨架上，阻止绝缘膜的形成并且可以使LiPSs进一步穿透到正极里[ |
| Fig.27 Schematic illustration of (a) a routine PP separator and (b) a Janus separator with a CGF layer. Without a CGF layer, the LiPSs that shuttled back accumulated at the separator/cathode interface to form a solid, nonactive, insulating passivation layer. With a CGF layer, the LiPSs were reduced and deposited on the conductive scaffolds, preventing the formation of the insulating film and enabling the further penetration of LiPSs into the cathode [ |
