Nanostructured Fe3O4/SWNT Electrode: Binder-Free and High-Rate Li-Ion Anode

Utilizing Fe3O4 nanorods as the active Li+ storage material and 5 wt% carbon single‐walled nanotubes (SWNTs) as a “conductive net,” a Li‐ion anode with a high reversible capacity of 1000 mAh g−1 (∼2000 mAh cm−3) at C rate is demonstrated. The electrodes exhibit high‐rate capability and stable capaci...

Description
Summary:Utilizing Fe3O4 nanorods as the active Li+ storage material and 5 wt% carbon single‐walled nanotubes (SWNTs) as a “conductive net,” a Li‐ion anode with a high reversible capacity of 1000 mAh g−1 (∼2000 mAh cm−3) at C rate is demonstrated. The electrodes exhibit high‐rate capability and stable capacities of 800 mAh g−1 at 5C and ∼600 mAh g−1 at 10C.
