Figure 5. Development of polymeric binders for Ni-rich cathodes to mitigate particle degradation. (A) Schematic illustration of the SNH-applied cathode structure. (B) XPS analyses of SNH and PVDF electrodes after charge/discharge cycling in F 1s (left) and C 1s (right) regions. (C) Cross-sectional SEM and (D) TEM images of SNH and PVDF electrodes after cycling. Reproduced with permission^[92]. (E) Synthesis of PNCI terpolymers and schematic representation of the functional contributions of individual moieties in the PNCI# binder system. (F) Concentrations of Ni, Co, and Mn ions deposited on the surface of Li metal anodes in PVDF and PNCI333 cells, determined by ICP-MS. Reproduced with permission^[93].
