摘要：

LiFePO4 powders were synthesized under two different conditions (hydrothermal or mechanochemical activation) using iron(II) phosphate and lithium phosphate as starting materials. The samples were characterized by X-ray diffraction, chemical titration, and their electrochemical performance was investigated in terms of cycling behavior and impedance response. We also report the benefit of introducing an electronic conductor precursor (typically a sucrose) during or after the synthesis to overcome the poor charge transfer associated to the lithium iron phosphate.
