Controlled synthesis of Mn_3O_4/RGO nanocomposites with enhanced lithium-storage performance

摘要

In this study, Mn_3O_4 nanocrystals supported by reduced graphene oxide (RGO) nanosheets have been successfully prepared in one step by a facile hydrother-mal method. The characterization results show that the well-crystallized Mn_3O_4 monocrystals are uniformly dispersed on the surface of RGO nanosheets. Further studies indicate that the synergistic effect between RGO nanosheets and Mn_3O_4 nanocrystals not only alleviates mechanical deformation of the composite but also improves the transport of ions and electrons. As a result, the resulting Mn_3O_4/RGO nanocomposites deliver a high specific capacity, along with excellent cycle stability and rate performance when used as anode materials for lithium-ion batteries.
