Li‐rich transition‐metal oxides with a disordered rocksalt structure can be regarded as promising candidates for an electrode material of lithium‐ion batteries. Among the oxides, the study by Naoto Kitamura et al. (article number 2000112 ) focuses on Li 3 NbO 4 ‐based materials and investigates the local structures by a reverse Monte Carlo modeling using neutron and synchrotron X‐ray total scattering data. It is clarified that local distortion around Nb is significantly large and that Li tends to be surrounded by Nb. From these results, it can be considered that Li diffusion is disturbed by the cation with higher valence.
