Abstract
(Figure Presented) Aggregated antisite cations of iron (see picture, red) in the lithium sites of doped lithium iron phosphate (LiFePO4) are arranged preferentially along the b axis. To probe the peculiar array of the defects, Z-contrast STEM with a spherical-aberration correction is utilized. The images obtained using Z-contrast STEM suggest that the distribution of antisite defects in LiFePO4 can be adjusted for improved lithium ion transport.
