All-solid-state lithium batteries with NMC<sub>955</sub> cathodes: PVDF-free formulation with SBR and capacity recovery insights

Figure 6. TOF-SIMS analysis of “Fresh” (pristine) and cycled electrode samples. (A) Negative ion spectra of pristine and cycled electrode samples focusing on peaks corresponding to PS-/PO2- (left), S2O-/SO3- (center), and S3-/SO4- (right); (B) Ion images of secondary ions representing sulfates (top left), LiNMC955 (top right), LPSCl (bottom left) and SBR binder (bottom right); (C) Three-colour overlay image (from B) showing LPSCl in red, sulfates in green and LiNMC955 in blue. Field of view 100 × 100 µm2. TOF-SIMS: Time-of-flight secondary ion mass spectrometry; LPSCl: Li6PS5Cl.
