Structure evolution of Li1.2Ni0.333Ti0.333Mo0.133O2 (LN20) and Li1.15Ni0.45Ti0.3Mo0.1O1.85F0.15 (LNF15) upon first charge (1st c) and discharge (1st dc). a In situ X-ray diffraction (XRD) patterns, b voltage profile (black line), and the lattice parameter (blue dot) of LN20. c In situ XRD patterns, d voltage profile (black line), and the lattice parameter (blue dot) of LNF15. In situ XRD cells were cycled at 10 mA g–1 at room temperature between 1.5 and 4.6 V
