| 제목 | Synthesis of SiOx and SnO2 impregnated OMC composites for lithium ion battery anode |
| 초록 | As the demand for energy storage system increases, the development of Li secondary batteries is becoming more important. Li-ion battery is the most successfully used because of their relatively high energy density, good cycle life, and good power performance. Commonly used anode material in LIB is graphite, which has low theoretical capacity. The ordered mesoporous carbon (OMC) has been proven as one of the alternative anode materials with higher capacity than that of graphite, high electric conductivity, and improved rate capability. Another attractive anode materials are SnO2 and SiOx, which exhibit higher capacity. Here, we introduced OMC/SiOx+SnO2 composites by impregnation of SiOx followed by further impregnation of SnO2. The structure of synthesized material is characterized by XRD, N2-sorption, SEM, EDS. By electrochemical test, The OMC/SiOx+SnO2 composites showed a higher electrochemical performance and rate ability than OMC/SiOx or OMC/SnO2 composites, or just OMC itself. |
