Electrochemical impedance spectra (EIS) for lithium ion deinsertion and insertion in olivine LiFePO4 were obtained at different potentials and different temperatures during charge-discharge cycle.The results revealed that three semicircles and a slightly inclined line appear successively as the frequency decreases in the Nyquist diagram (Fig.1).
