Abstract

Fe3O4@C core-shell nanorings (R-Fe3O4@C) were fabricated by a synchronous reduction and carbon deposition process. As the anodes for lithium-ion batteries, these R-Fe3O4@C exhibit a high capacity, excellent cycling stability and good rate performance. This ring-shaped core-shell nanostructure design may pave the way to enhance electrochemical performances of electrode materials.
