Figure 13. APT analysis of corroded LiNi0.8Mn0.1Co0.1O2 (NMC811) particle. (A) Scanning electron microscope image of the NMC811 particles. (B) Schematic illustrations of the APT specimen preparation method. The oxide layer of interest, as a corrosion product, is shown in orange. (C) 3-D reconstruction of the APT dataset of the tip incorporating the oxide later. (D) 1-D elemental concentration profile of the NMC oxide product from a cylindrical region of interest with 5 nm in diameter and 50 nm in length.
