Synthesis of Porous Mn2O3 Embedded in Reduced Graphene Oxide as Advanced Anode Materials for Lithium Storage

Abstract

We described a facile method to prepare porous manganese oxides (Mn2O3) embedded in reduced graphene oxide (rGO). Firstly, the porous Mn2O3 nanospheres were achieved from the coordination self-assembled aggregations (referred as Mn(OAc)2-C-8), serving as precursor via calcination treatment, followed by a graphene coating approach. The reduced graphene oxide coating Mn2O3 (Mn2O3@rGO) composites not only provide superior conductivity and prevent large volume expansion resulting in settling the challenges of pure Mn2O3 nanospheres, but also remedy the imperfection of inferior specific capacity of traditional graphite materials. When evaluated as an anode for lithium-ion batteries (LIBs), the Mn2O3@rGO electrode exhibits a high initial specific capacity (1684.9 mAh g-1), excellent cycling performance (1207.9 mAh g-1 over 150 cycles at a current density of 0.1 A g-1), high coulombic efficiency (99 % after 150 cycles) as well as high rate capacity (730.0 mAh g-1 over 150 cycles at 1 A g-1). The unique structural design and synergistic effect can offer a practical conception for the development of new next generation of LIBs.
