title: 3D graphene foams cross-linked with pre-encapsulated Fe3O4 nanospheres for enhanced lithium storage.
abstract: Electrostatic assembly between Fe3O4 nanospheres and graphene oxide, and subsequent hydrothermal assembly with additional graphene sheets, leads to Fe3O4 nanospheres encapsulated in the graphene shells and interconnected by the graphene networks. Such 3D Fe3O4 /graphene foams exhibit enhanced lithium storage with excellent cycling performance and rate capability.
