摘要
The lithiation behavior of LiFePO4 in saturated LiNO3 solution is investigated by analyses of cyclic voltammetry(CV), potentiostatic intermittent titration(PITT) and electrochemical impedance spectra(EIS), The results show that LiFePO4 has good electrochemical reversibility in saturated LiNO3 solution. The lithium diffusion coefficients measured by PITT vary with potential, get its lowest value at the beginning of phase transition. EIS show that phase transition will baffle lithium diffusion in electrode.
