ZnO has attracted enormous research interest as anode material in lithium ion batteries due to its large theoretical capacity. Unfortunately, the development of ZnO-based anode materials is greatly bottlenecked by their poor capacity retention and limited cyclic life. Herein, ingeniously designed 3D graphene encapsulated ZnO-NiO-CuO double-shelled hollow microspheres (DSHM@RGO) have been prepared by a facile surfactant-assisted assembly method. Benefiting from their unique features including the large specific surface area, the double-shelled hollow architecture, the modification of graphene and the nanoscale building blocks, the DSHM@RGO anode exhibits enhanced electrochemical performances. A high reversible capacity of 559 mA h g(-1) is delivered after 100 cycles at a current density of 1.0 A g(-1). When cycled at a large current density of 3.0 Ag-1, the as-obtained DHSM@RGO still delivers a relative high specific capacity of 366 mA h g(-1). (C) 2018 Elsevier B.V. All rights reserved.
