In this manuscript,we have demonstrated the delicate design and synthesis of bimetallic oxides nanoparticles derived from metal-oleate complex embedded in 3D graphene networks (MnO/CoMn2O4 (∈) GN),as an anode material for lithium ion batteries.The novel synthesis of the MnO/CoMn2O4 (∈) GN consists of thermal decomposition of metal-oleate complex containing cobalt and manganese metals and oleate ligand,forming bimetallic oxides nanoparticles,followed by a self-assembly route with reduced graphene oxides.The MnO/CoMn2O4 (∈) GN composite,with a unique architecture of bimetallic oxides nanoparticles encapsulated in 3D graphene networks,rationally integrates several benefits including shortening the diffusion path of Li+ ions,improving electrical conductivity and mitigating volume variation during cycling.Studies show that the electrochemical reaction processes of MnO/CoMn2O4 (∈) GN electrodes are dominated by the pseudocapacitive behavior,leading to fast Li+ charge/discharge reactions.As a result,the MnO/CoMn2O4 (∈) GN manifests high initial specific capacity,stable cycling performance,and excellent rate capability.
