a The (111) plane of LiTi2O4 showing the titanium kagome sublattice inherent to the spinel structure. b Side-view of the (111) plane shown in a, highlighting the three-dimensional nature of the geometric frustration in LiTi2O4. c Resistivity ρ vs temperature of LiTi2O4 with magnetic field (0 to 9 T) parallel and perpendicular to the sample. d Large field-of-view HAADF-STEM image of LiTi2O4 showing uniform crystallinity over a large area. e Local HAADF-STEM image of LiTi2O4 overlaid with the corresponding atoms.
