Facile synthesis of graphene-supported mesoporous Mn3O4 nanosheets with a high-performance in Li-ion batteries

We report a room-temperature, facile and scalable strategy for the synthesis of Mn3O4 nanosheet/graphene nanocomposites. An important characteristic of these Mn3O4 nanosheets is their mesoporous nature and they have mesopores which are similar to 4 nm in size. Such nanocomposites exhibit a high performance in lithium-ion batteries by virtue of this advantageous structural feature.
