Abstract

We report a simple fabrication process for a stainless steel metal fibril-supported Fe₂O₃ (Fe₂O₃/SF) material as a lithium battery anode. Utilizing the well-developed 3D structure of Fe₂O₃/SF, the material shows not only a superior rate capability but also extremely long cycle life (2000 cycles), even at a high current density.
