Fig. 6: The role of LaTMO3 surface protection on the durability of the 5 V-class LIBs.
From: Epitaxial growth of an atom-thin layer on a LiNi0.5Mn1.5O4 cathode for stable Li-ion battery cycling
a Ex situ post-mortem Synchrotron XRD measurement showing the LNMO (220) peak and the LaTMO3 cubic (110) reflection for LNMO-C0.5La cathodes before and after cycling in the 3.4–4.8 V full cells. b Ex situ post-mortem Raman spectra of the graphite anodes harvested from cycled full cells using LNMO and LNMO-C0.5La cathodes. c, d Ex situ post-mortem EDS spectra of the cycled graphite anodes coupled with LNMO (c) and LNMO-C0.5La (d). e Schematic of the effect of the suppressed TM dissolution on the preservation of graphite anode. All the electrodes were collected from full cells at discharged state after 1000 cycles at 290 mA g−1 under 26 °C.
