show relatively higher ID/IG ratios (>1.00). Higher ID/IG points to the existence of more defects and higher structural disorder in the surface of the spots where Spectra 4, 5, and 6 are captured. This together with the presence of D* and D`` in these spectra suggests that the surface of scanned particles (Spectrum 4, 5, and 6 in Fig. ) could be covered with a layer of disordered carbon which is used as a coating for graphite anode to protect it from electrolyte attack. Furthermore, the presence of PVDF binder on graphite surfaces, as shown by EDX analysis (Fig. ), could also contribute to the formation of additional disorder peaks (as indicated by Fig. ).
