A hybrid phase-transition model of olivine LiFePO4 for the charge and discharge processes

Generally, it is well known that the lithium-ion diffusion in olivine LixFePO4 is correlated with the phase transition dominated by a domino-cascade model instead of a core–shell model. Based on the experiment result, we firstly found that the linear Warburg region of electrochemical impedance spect...
