Influence on Electrochemical Performance of LiMnPO₄ by Y Doping Using Low Combustion Synthesis Method

Abstract:

The olivine LiMnPO₄ used as cathode materials was synthesized by the low combustion synthesis method, and modified by doping Y. Testing of X-ray diffraction (XRD),scanning electron microscopy (SEM),charge-discharge measurements was carried out for LiMnPO₄/C cathode materials and the modified materials. The synthesized materials doping by Y exhibited standard olivine structure, nano-sized particles, discharge capacity of 122.9mAh.g-1 and good cycling performance. These results indicated that less Y doping could improve electrochemical kinetics of lithium ion extraction/insertion and significantly enhanced electrochemical activity.
