Sažetak
In this research, it present a way through which to identify the structure of Nickel-Cobalt Manganese (NCM) cathode material by means of Infrared spectroscopy (IR spectroscopy). Based on the IR spectra of the initial cathode material, there are intense adsorption peaks that stretch the C=C bonds in the graphite structure. In addition, the peaks of 3000-3700 cm-1 are not observed, which proves the absence of O-H functional groups. After annealing, it was noticed that the surface structure of NCM has been changed. The appeared peaks indicate the recovery of NCM cathode material. The peak intensities of stretching vibration at 3410 cm-1 correspond to N-H groups, vibrational peak at 1650 cm-1 is related to C-C and C=O groups and vibrational peak at 1080 cm-1 characterizes the presence of C-N or C-O groups.
