| Abstract: |
| LiMnPO4/C composite as a cathode materials for lithium ion batteries was synthesized via a Sol-Gel method using cheap inorganic salt while citric acid as a carbon source. Crystalline structure and morphology of the composite were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM). The results indicate that the LiMnPO4/C composite is well crystallized as an olivine structure without any detectable impurity phase. Electrochemical performance of the material prepared was better when the annealing temperature was set to 650℃ bt two-stage sintering, its initial discharge capacities was 142.8 mAh/g at rates of 0.05C under room temperature, and it remained 112.4 mAh/g after 20 cycles. |
