Graphitized stacked-cup carbon nanofibers as anode materials for lithium-ion batteries

- The anodic performance of CNFs improves significantly after HTT (1800-2800 °C)
- The cell capacity increases progressively with the structural order of the CNFs
- Extended cycling at C/10 provides capacities up to 300 mAh g−1 with efficiency > 90%
- Due to their nanometric size, the CNFs show good rate capability (C/10-2C)
