Figure 7. Representative aqueous binders for high-voltage lithium oxide cathode materials. (A) Schematic of different interactions between LCO and PVDF/DSL binders and their effects on surface stability. (B) Cycling performance of LCO electrodes with PVDF and DSL binders at 0.5C and 2.8-4.6 V. (C) In situ X-ray diffraction measurements with (003) diffraction peak during the first charge-discharge cycle at 0.1 C. (D) Crystal structure under high voltage. (E) CV curves. (F) SEM images (cross-sectional view) after 50 cycles for two LCO electrodes. Reproduced from Ref.[166] with permission from Wiley-VCH. (G) Schematic of generation of the γ-PGFO binder with chemical structure. Reproduced from Ref.[172] with permission from Springer Nature. (H) Schematic of effects of P(MVE-LMA) and PVDF binders on LNMO electrode during cycling. Reproduced from Ref.[171] with permission from the Royal Society of Chemistry.
