3D internal structure of rechargeable batteries revealed for the first time
Graphite crystal model sample and SEI formation on the edge section vs basal plane. a Optical image of a cross-section HOPG model sample. b Raman spectra at polished section and basal plane of as-prepared model sample. c First two cyclic voltammetry (CV) curves of model sample. (0.5 mV/s scan rate, 1 M LiPF6 salt in the EC/DMC = 1:1 vol% electrolyte) (d) G band of operando Raman spectra at section area upon the first lithium intercalation. e–h Dynamic topography evolutions during the 1st CV scan in ethylene…
