Effect of Doping Cation Valencies on Low Temperature Performance of LiFePO₄/C

Abstract:

The doped and undoped LiFePO₄/C samples are prepared by two-step solid-state reaction. The X Ray Diffraction (XRD) results indicate that metal ions are successfully doped in LiFePO4 without any unexpected phase. The Scanning Electron Microscope (SEM) shows that the particle morphologies of samples are near-spherical with about 200-300nm size which can be observed in all samples. The electrochemical tests indicate that doping oversize ions will increase electrode polarization. The limitation of the Li+ migration is intensified by doping metal ions with high valence. LiFePO₄/C samples doped with Mn2+ and Ti⁴⁺ behave better at low temperature, especially the one doped with Ti⁴⁺. Battery with this Ti⁴⁺ doped material can yield 77mAhg-1 when discharge at -20°C and 0.5C, about 26mAhg-1 higher than the undoped one.
