Nanostructuring for the advanced nanoscale Si anodes. (a) Schematic of morphological changes that occur in SiNWs during electrochemical cycling. (b) TEM data for SiNWs at different stages of the first charge. Reproduced with permission from ref (33). Copyright 2008 Springer Nature. (c) Schematic illustration of the Si@void@C electrode and magnified schematic of an individual Si@void@C particle showing that SiNP expands without breaking the carbon coating or disrupting the SEI layer on the outer surface. (d) In situ TEM images of Si@void@C in a pristine state (0 s) and after full lithiation. Adapted with permission from ref (34). Copyright 2012 American Chemical Society. (e) Time-lapse in situ TEM images of 2DSi@C and (f) snapshots of deformation morphologies predicted by the chemomechanical model for two lithiation cycles. Reproduced with permission from ref (2).
