a Charge and discharge voltage profiles for the 1st cycle of LTMO, LTMOF, and LTMO-500 (LTMO annealed at 500 °C for 60 h) cathodes in half-cells cycled between 1.5 and 4.8 V at a current density of 20 mAg−1. b Electron diffraction pattern (top) of LTMO-500 and the corresponding schematic (bottom). c Atomic-scale STEM Z-contrast image of LTMO-500 (leftmost) and corresponding FFT (second left) and intensity color maps showing the distribution of both Li-rich (green) and TM-rich (red) nanoregions (third left) and showing only the Li-rich (green) nanoregions (rightmost). d Atomic models for the highlighted regions in the intensity map in (c) and corresponding schematic FFT patterns.
