Abstract: 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.

Keywords: aqueous lithium-ion battery LiFePO₄ diffusion coefficient phase transition
