▎ 摘　　要

A simple synthetic approach for graphene-templated nanostructured MnO2 nanowires self-inserted with Co3O4 nanocages is proposed in this work. The Co3O4 nanocages were penetrated in situ by MnO2 nanowires. As an anode, the as-obtained MnO2-Co3O4-RGO composite exhibits remarkable enhanced performance compared with the MnO2-RGO and Co3O4-RGO samples. The MnO2-Co3O4-RGO electrode delivers a reversible capacity of up to 577.4mAhg(-1) after 400 cycles at 500mAg(-1) and the Coulombic efficiency of MnO2-Co3O4-RGO is about 96%.
