Green and controlled synthesis of Cu2O-graphene hierarchical nanohybrids as high-performance anode materials for lithium-ion batteries via an ultrasound assisted approach.

A low-cost, fast, facile, green method, namely an ultrasound assisted approach, has been developed for the controlled synthesis of Cu(2)O-graphene hybrid nanomaterials. By the protection of graphene nanosheets, the as-obtained anode material exhibited enhanced lithium ion battery performance.
