Horizontal slices at fixed distances, n·L = n·9.75 μm (L represents the total length of 30 voxels, 9.75 μm) from the Cu substrate are taken from each 3D tomogram (1–10 L), same tomogram as those in Supplementary Figs. 3 and 4. a Slices taken at 3 L (29.25 μm from the Cu substrate) are shown as an example. Dark features are deposited Li, and gray region is liquid electrolyte. b Evolution of area of segmented Li at different distances from the Cu surface (i.e., in each slice) during plating/stripping at 0.5 and 1.0 mA cm–2. The white areas between colored areas indicate the tomograms which are taken after plating or stripping process.
