FIGURE 5 Microstructural evolution of the cycled LCO cathode with different SHPEs. (a, b) In situ DRT data for different SOCs of LCO|SHPEs|Li during the charge (a) and discharge (b) processes. (c) Cross-sectional SEM images and EDS maps of the LCO cathode after 100 cycles. (d) HR-TEM images and mappings of the LCO cathode after 100 cycles. (e, f) Depth-profiled F 1s (e) and B 1s (f) XPS data of the CEI in LCO|B-F-SHPE|Li. (g) TOF- SIMS 3D reconstruction of the species fragments in the CEI in LCO|B-F-SHPE|Li. (h) Normalized Co K-edge XANES spectra of cycled LCO cathodes. (i–l) HR-TEM images of CEI and internal structure of LCO in LCO|F-SHPE|Li (i, k) and LCO|B-F-SHPE|Li (j, l).
