© 2017, King Fahd University of Petroleum & Minerals. 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 3O 4 nanoparticles (Mn 3O 4–GNS) composite, as well as Mn 3O 4 nanosheet, were synthesized via a facile hydrothermal method. The Mn 3O 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 3O 4, the buffer and confine effects of graphene nanosheets (GNSs) and the distinctive synergistic effect between two components of GNS and metal oxides.
