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.
