The various commercial graphite structures and their lithium intercalation properties were investigated using X-ray diffraction (XRD) and electrochemical voltage spectroscopy (EVS) techniques. It has been found

The XRD analysis of black mass samples (Fig. 2) confirmed the presence of graphite, 3R (rhombohedral, ICDD PFD-4 04-007-2076) and 2H (hexagonal, ICDD PFD-4 04–014-0362) with their ratio being close to equal (Table S1). It indicates that both black mass concentrates mostly contain ...
The XRD pattern of the TGSH revealed that talc-2M, actinolite, graphite and calcite are the dominant crystalline metamorphic phases, in association with a minor crystalline phase of quartz (Fig.1a). The presence of these phases explains the high content of the above-mentioned major oxides in th...
GIAXRD data support that the co-existence of both crystalline structures of 2H and 3R in HOPG. The carbon bond breaking in 2H and 3R is different and depends on the angle of incidence. Most broken carbon bonds form damaged aromatic rings near the surface of HOPG....
The XRD characterization of SG, AL, and RG are compared with commercial graphite. As displayed in Fig. 2 (a-b), all samples display the strongest Conclusions and outlook In conclusion, we have demonstrated a facile recycling perspective using simple acid treatment and thermal anneal to transform...
