Figure 4: Core–shell structure of the CCNEs.
From: Freestanding three-dimensional core–shell nanoarrays for lithium-ion battery anodes
s.e.m. (a) and TEM (b) micrographs of the CCNE after 30 min deposition. TEM micrographs of the CCNEs after 20 min (c) and 40 min (d) deposition. STEM image (e) and EDX elemental mapping (f) of the core–shell nanocable. High-resolution TEM images (g–i) of the nanoscale after 5 min deposition, and corresponding micro-mechanism models (j). Scale bar in a, 1 um; scale bars in b–f, 200 nm; scale bar in g, 40 nm; scale bars in h and i, 5 nm.
