The electrochemical impedance of samples L-NM 26 (black color), L-NM 35 (green color) and L-NM 44 (red color) at a charge constant current of 20 mA g 1 (1C = 200 mA g 1 ) for 4h and comparative electrochemical impedance performed of samples after 2nd and 10th cycles. The right side of the Nyquist diagrams for each sample displays experimental values (scatter) alongside fitted values (lines), while the lower section of the Bode diagram presents the corresponding data. In the equivalent circuit, Rs represents the ohmic/electrolyte resistance, RCEI the cathode/electrolyte interphase resistance, Rct1 and Rct2 the charge-transfer resistance contributions, φ CEI, φ dl1, and φ dl2 the corresponding constant-phase elements, W the Warburg diffusion element, and τ CEI, τ dl1, and τ dl2 the characteristic relaxation times associated with the corresponding impedance processes.
