Fe3O4@C核壳纳米环（R-Fe3O4@C）是通过同步还原和碳沉积过程制备的。作为锂离子电池负极，这些R-Fe3O4@C表现出高容量、优异的循环稳定性和良好的倍率性能。这种环形核壳纳米结构设计可能为增强电极材料的电化学性能铺平道路。
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.
