Direct observation of light elements (Li and O) in oxygen‐deficient lithium manganese spinel by spherical aberration‐corrected scanning transmission electron microscopy is reported. A previously unknown ordered structure was revealed by annular dark‐field (ADF) imaging of oxygen columns, while Li ions are visualized successfully by annular bright‐field (ABF) imaging (see picture).
