Fig. 6. Non-homogeneous distribution of Li and formation along line-shaped defects after charge–discharge cycles.
a, b APT Li map and composition profile across line-shaped Li-enriched regions. The Li concentration is locally high, following a line shape. Error bars show the standard deviation of each dataset. c, d STEM-HAADF images of the anti-phase domain boundary (APDB) (c) and the arrangement of APDB in the grain (d). Inset in (c) is a schematic illustration of APDB.
