Fig. shows the SEM images and energy dispersive X-ray (EDX) analysis of the three BM samples, where the particles can be distinctively categorized into two types based on their morphological features: graphite anode particles and NMC CAM particles. Fig. , Fig. , and Fig. show the SEM images of graphite particles for BM1, BM2, and BM3, respectively. These graphite particles for all three BM samples are irregular-shaped and have slightly rough morphology with deposition of small brighter particles on the surface, which are primarily transition metals i.e., Ni, Mn, and Co (as shown in Fig. ). EDX analysis of these graphite particles reveals that it is 90-98 wt. % carbon with small amounts of transition metals and fluorine (Fig. ).
