The Nyquist plots for all materials were studied in the frequency between 10 6 to 10 -2 Hz an amplitude of 5 mV as shown in Fig. . To study the kinetics and diffusion mechanisms, all the electrodes were cycled five times at 0.1 C for the activation. The first semicircle observed in all plots represents the charge-transfer resistance (Rct) in the electrode-electrolyte interface followed by the Warburg impedance (Zw) denotes the diffusion. By analyzing and fitting the obtained EIS plots, the 0.1NC-NCM811 electrode behaves as an excellent fast charge transfer in the electrodeelectrolyte medium by registering a lower Rct of 38.6 Ohm. Whereas, for bare NCM, 0.05NC-NCM811, and 0.15NC-NCM811 materials, the Rct values are found to be at 69.9, 65.8, and 67.5
