Abstract

LiFe_0.8Mn_0.1Mg_0.1PO₄/C and LiFePO₄/C were respectively prepared using MnCO₃ and (MgCO₃)₄ ·Mg(OH)₂·5H₂O, glucose as doping starting materials by high-temperature solid state reaction under Ar atmosphere. The prepared composites were characterized by X-ray diffraction, scanning electron microscope and FT-IR spectroscopic, and electrochemical performance was investigated with constant current charge-discharge experiment. The results showed that LiFe_0.8Mn_0.1Mg_0.1PO₄/C preserved olivine structure with no impurity. Compared with LiFePO₄/C, the electronic conductivity of LiFe_0.8Mn_0.1Mg_0.1PO₄/C has been improved. LiFe_0.8Mn_0.1Mg_0.1PO₄/C had a reversible capacity of 131mAh/g at 0.1C discharge rate, and showed good electrochemical properties.
