Abstract Fe 3 O 4 @C composite was designed and synthesized by a facile one-step solvothermal route as an anode material for Li-ion batteries (LIBs). The carbon shell can effectively prevent the aggregation and buffer the volume expansion during charge/discharge process. The electrochemical performance displays that the Fe 3 O 4 @C composite exhibits high reversible capacity and good cycling performance. In particular, it displays excellent cycling stability at 2 C rate (640.5/642.2 mA h g−1 after 1000 cycles). The results indicate a simple and useful route to prepare Fe 3 O 4 @C composite as a promising LIBs anode material. Graphical abstract Fe 3 O 4 @C composite with high reversible capacity and good cycling performance has been synthesized by a facile one-step solvothermal route as an anode material for Li-ion batteries (LIBs). fx1 Highlights • Fe 3 O 4 @C composite has been synthesized by a facile one-step solvothermal route. • Fe 3 O 4 @C composite has been studied as an anode material for LIBs. • Fe 3 O 4 @C composite displays high reversible capacity and good cycling performance.
