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).
