| Abstract: | The charcoal-protected method was used in the preparation of lithium iron phosphate for lithium-ion battery cathode. The LiFePO4/C material was synthesized by carbothermal reduction, FePO4·2H2O, Li2CO3 and cane sugar as raw material. The samples were analyzed by XRD, SEM and charge/discharge capability, and the result indicated that the charcoal-protected method was feasible and its primary dis＇charge capacity was 134 mAh/g and the buried charcoal atmosphere was more propitious to the synthesis of LiFePO4 than the inert atmosphere. |
