Nanostructured transitional metal oxides have received more and more attention as the electrode materials for lithium-ion batteries to achieve high specific capacity and good safety performance. In this paper, a graphene nanosheet-supported Mn 3 O 4 nanoparticles (Mn 3 O 4 –GNS) composite, as well as Mn 3 O 4 nanosheet, were synthesized via a facile hydrothermal method. The Mn 3 O 4 –GNS composite exhibits good electrochemical performances with high reversible specific capacity (an initial charge capacity of 969 mAh g - 1 at 93.6 mA g - 1 ), good cycling stability (a retained capacity of 646 mAh g - 1 after 60 cycles) and rate capability when used as the anode material for LIBs. The enhanced electrochemical performance could be attributed to the nanoscaled particles of Mn 3 O 4 , the buffer and confine effects of graphene nanosheets (GNSs) and the distinctive synergistic effect between two components of GNS and metal oxides.
