Figure 8. Double-sided bifunctional separators for Li-S batteries. (A) SEM images of the cycled Li-metal anodes disassembled from symmetrical cells with PP separator and the Al₂O₃-PE-CMC separator and polysulfide adsorption tests before and after adding CMC powder. (B) Long-term cycling performance of the LCL-TCL modified separator and the schematic of corresponding Li-S cells. (C) Configuration schematic of Li-S cells with Ce-MOF-808/PP separator, diffusion energy barrier of Li-ion of Ce-MOF-808, and the Li-Li symmetric cells voltage profiles.
