Figure 8. FTIR and post-cycling analysis: (A and B) FTIR characterization of the binders: (A) Comparison between CMC and CMC-PAA at higher wavenumber and (B) Comparison between CMC, PAA, and CMC-PAA at a lower wave number (The crosslinked was formed by heating at 150 °C for 2 h under vacuum); and (C and D) Post-cycling analysis of the electrodes: SEM images of (C) Electrode with CMC binder and (D) Electrode with c-CMC-PAA binder after 200 repeated cycles.
