| 제목 | Synthesis of LiFePO4 powder as a cathode material for Li-ion batteries by spray pyrolysis |
| 초록 | LiFePO4 particles as a cathode material for lithium ion batteries were prepared by the conventional spray pyrolysis. Because they were very sensitive to the reductive atmosphere, H2 5%/Ar 95% mixed gas was used as a carrier gas for both spray pyrolysis and post treatment. The reaction temperature was varied between 400 to 800℃ and prepared particles were post treated at 750℃ for 4 hours with the flow rate of 0.4 L/min to get LiFePO4 single phase. The morphology and crystallinity of the prepared particles were characterized by scanning electron microscope (SEM) and X-ray diffraction analysis. Doped lithium iron phosphate was prepared to improve their intrinsic low conductivity by the same method above and its conductivity at room temperature was characterized by 4-point probe method. |
