(1) and ( ) for all the electrodes was given. The derived results imply that the DLi for 0.1NC-NCM811 is 1.86 × 10 -11 cm 2 s -1 which is much greater than the bare NCM811 2.32 × 10 -12 cm 2 s - electrode and provides favorable kinetics for Li-ion diffusion. The decrease of DLi in 0.15NC-NCM811 is due to the presence of thicker N and C coating which impedes the effective movement of Li-ions towards the layered cathode structure. In addition, cyclic voltammetry (CV) results for bare and modified samples shown in Fig. , it is observed that 0.1NC-NCM811 has enhanced redox current peaks than all other samples indicating its better electrochemical behavior.
