For polycrystalline NCM, two identical cells were charged at constant current (CC) to cutoff potentials of 3.7 V versus Li + /Li and 4.2 V versus Li + /Li, respectively. As a consequence, polycrystalline NCM particles in those cells charged to the higher voltage (HV) were affected by cracks induced by the processes discussed above.
The degradation mechanisms related to the NCM cathode are outlined in Fig. 2 and mainly stem from two distinct sources – the synthesis of cathode material and the operation of battery (lithiation-delithiation of cathode) once the cathode is incorporated within the cell.
