Figure 5. (A) Schematic of advantages and challenges of using WSEs in Li-S batteries. (B, D and I) Chemical structures of the FE cosolvents, CIP/SSIP ratio of FSI- determined via Raman analysis, and atomic compositions of the SEIs in the DME, DME-ETFE, DME-BTFE, and DME-TFTFE electrolytes after 36 cycles of operation. These figures are quoted and reproduced from Kim et al.[62] Copyright 2024, Wiley-VCH GmbH; (C, G and H) Electrostatic potentials of the moderately solvating solvent (DME) and weakly solvating solvent (HME) (isovalue: 0.001 a.u.), shuttle currents at various potentiostatic charging voltages, and profiles of activation polarization vs. DOD and their comparison at DOD = 0.3 (the inset figure). These figures are quoted and reproduced from Li et al.[63] Copyright 2024, American Chemical Society; (E and F) Raman spectra along with the distribution of free TFSI- (blue line), SSIPs (olive line), CIPs (light red line), and AGGs (green line) within the REE and LWE electrolyte systems.
