(A) Nyquist plots of the ECF under different cycling conditions: as-assembled cycle and after 300 cycles. Equivalent circuits for fitting Nyquist plots (B) before and (C) after cycling. R1: the internal series resistance of the cell; R2: the charge-transfer resistance; and R3: the SEI film resistance.
