Figure 9. (A) Illustration of the Li ion transport pathway, LCD, SEI, and Li deposition morphology in PVDF HFP-based polymer electrolyte; (B) Diagram depicting the Li ion transport pathway in LPS_x and the interaction between PVDF-HFP and WS_x, and the representation of LCD, SEI, and Li deposition morphology in LPS_x CPE; (C) Effects of band engineering on the increase of p-band, s-p hybridization on the surface of WS_x, and the corresponding LiFSI dissociation and absorption processes^[92].
