| 제목 | High-coulombic-efficiency Si/Graphene/IL-derived carbon microspheres composite anode for Lithium-ion batteries |
| 초록 | Li-ion batteries are considered the most promising power sources for advanced energy storage facilities. In particular, Si has been considered as a promising anode material for due to its fascinating features. However, a large volume change of Si during cycles causes severe fading in cycles. Recent researches have focused on the solution of this problem. The most effective strategy is to use graphene as the buffering matrix. In this composites, graphene acts not only as the buffering matrix but also as a conductive network for Si, resulting in superior performances. However, most these composites exhibit very low initial coulombic efficiency(C.E.). Therefore, it is critical to develop high C.E. Si-based anode materials that are suitable for practical use. Herein, we developed a high-C.E. Si-based hybrid anode material based on a combination of graphene and ionic liquid. It exhibits enhanced coulombic efficiency and superior performances. More details will be discussed at the meeting. |
