Carbon Nanotubes Branched on Three-Dimensional, Nitrogen-Incorporated Reduced Graphene Oxide/Iron Oxide Hybrid Architectures for Lithium Ion Battery Anode |
| 초록 |
The carbon nanotubes (CNT) branches on three-dimensional nitrogen doped graphene oxide (NG) has been successfully synthesized via microwave self-assembly method. Compared with the pristine RGO, the CNTs can be more readily and uniformly grown on the 3D NG surfaces due to the good electronic conductivity by N-type configurations. As demonstrated by the electrochemical performances, the discharge capacity of the 3D CNT@NG-Fe is 1208 mAh g-1 at 50 mA g-1 which is greater than 890 and 820 mAh g-1 of the CNT@G-Fe and NG. After 130 cycles at 100 mA g-1, the capacity gradually increases to 1020 mAh g-1 with the Coulombic efficiency of ＞ 98.5 % due to the hierarchical structure and formation of electrochemical active site by nitrogen doping. |
