[Display omitted] •Co3O4@CuO microspheres are prepared and modified with graphene quantum dots (GQDs).•The Co3O4@CuO@GQDs exhibits a unique yolk-shell and mesoporous structure.•The modification of GQDs boosts the lithium storage behavior for Co3O4@CuO. In this report, we present the synthesis of yol...
