Hierarchical MoO₂/rGO Composite as a High-Performance Anode Material for Lithium-Ion Batteries

摘要

The rational design of composites containing transition metal oxides and graphene has received great attention because of the excellent electrochemical performance and potential applications of these materials in the energy storage field. The introduction of graphene promotes the electronic conductivity and lithium or sodium storage capacity of the hybrid electrode. We report the synthesis of a hierarchical MoO2/rGO composite. As a proof-of-concept application, the as-synthesized MoO2/rGO exhibits good electrochemical performance including a high specific capacity and a high rate stability.
