Feeling the fiber: A composite material comprising Fe3O4 particles anchored onto carbon nanofibers is formed through a simple, solvent-free, two-step process. The carbon fibers self-organize in a helical manner during the pyrolysis process. Synergistic effects between the Fe3O4 and the carbon support lead to a composite with high capacity, and good cycling stability and rate capability.
