Graphitic carbons (mostly soft carbons) can take up different morphologies
depending on the method of preparation and carbon source [56]. Lampe-
Onnerud et al. have reported carbons of different morphologies: beads,
bres, akes and potatoes (as shown in the SEM images in Figure 7.41, and
the results summarised in Table 7.6 and Figure 7.42). The crystallite size of
beads and potatoes are around ~20 nm in the direction perpendicular to ‘gra-
phene planes’, where the akes are extended to ~100 nm in the ...
