| 제목 | Enhanced cycle property of LiCoO2 coated with fluorine compound |
| 초록 | LiCoO2 have been used as cathode material for Li-ion batteries, because of its high capacity. However, LiCoO2 is less safe than other positive electrode materials. Because of the dissolution of cobalt and undesired reaction, the capacity fading and performance degradation of the cathode occurs in the higher charging voltage region(＞4.4V) In this study, to overcome LiCoO2’s drawback, ultra fine LiCoO2 particles were synthesized using sol-gel method and as-prepared particles were coated with fluorine compound through spray pyrolysis. Synthesized active material was analyzed by SEM, XRD. Coin type cell was fabricated and test was conducted. |
