Electrochemical performance of hierarchical heteroatom enriched porous carbons for lithium-ion batteries |
| 초록 |
Li-ion batteries (LIBs) are currently being used as one of the most important energy-storage devices for portable electronics and electrical vehicles. However, the conventional graphite-based anode materials used in commercial LIBs have low capacity (372 mAh/g) because of the limited Li-ion-storage sites (LiC6) within the sp2 carbon hexahedrons and relatively low rate capability, which results from the poor intercalation kinetics in the layered graphitic structures. So, hierarchical heteroatom-enriched porous carbon has been used as support anode materials, which has numerous heteroatoms. In this study, the prepared anode materials showed superior electrochemical performance, a high reversible capacity, good rate performance, and great cycle stability as an anode material for LIBs. |
