title: Reduced Graphene-Wrapped MnO2 Nanowires Self-Inserted with Co3 O4 Nanocages: Remarkable Enhanced Performances for Lithium-Ion Anode Applications.
abstract: A simple synthetic approach for graphene-templated nanostructured MnO2 nanowires self-inserted with Co3 O4 nanocages is proposed in this work. The Co3 O4 nanocages were penetrated in situ by MnO2 nanowires. As an anode, the as-obtained MnO2 -Co3 O4 -RGO composite exhibits remarkable enhanced performance compared with the MnO2 -RGO and Co3 O4 -RGO samples. The MnO2 -Co3 O4 -RGO electrode delivers a reversible capacity of up to 577.4 mA h g(-1) after 400 cycles at 500 mA g(-1) and the Coulombic efficiency of MnO2 -Co3 O4 -RGO is about 96 %.
