Microwave-assisted synthesis of dual-conducting Cu2O@Cu-graphene system with improved electrochemical performance as anode material for lithium batteries.

Two by two: A low-cost, fast, and green microwave-assisted approach has been developed for the controlled synthesis of core-shell Cu2O@Cu/graphene hybrids. With the unique dual-conducting system consisting of graphene support and Cu layer on the surface of the Cu2O nanoparticles, the as-obtained hybrids exhibited significantly enhanced lithium ion battery performance as anode materials.
