Fig. 9: Characterizations of cycled NCA electrodes in FFT and FST electrolytes.
From: High voltage electrolytes for lithium-ion batteries with micro-sized silicon anodes
a–f Typical HR-TEM images of cycled NCA electrodes recovered from μSi||NCA full cells after 50 cycles with FFT (a) and FST (b) electrolytes; the atomic distribution of CEI element on the surface of the NCA electrodes cycled in different electrolytes, FFT (c), FST (d); XPS F1s (e) and O1s (f) surface spectra for NCA cathodes with FFT (upper) and FST (below) electrolytes, The relative intensity for all spectra was shown in arbitrary units (a.u.) without labeling the y-axis for clarity.
