Abstract A new structured Mn3O4@C composite is fabricated with carbon filled in the pores and coated on the surface of the porous Mn3O4. This anode material exhibits superior electrochemical properties including high initial coulombic efficiency, outstanding rate properties and cycle performance. The initial coulombic efficiency of this composite approach to 69.5%, and it delivers a capacity of nearly 420 mAh g−1 even at a discharge current of 1800 mA g−1. The outperforming results could be ascribed to the unique structure of the composite, which can provide meaningful guidance to the design of further anode materials.
