Abstract: A unique flexible configuration with ordered porous rice ball‐like ZnCo2O4 (ZCO) microspheres embedded in reduced graphene oxide (rGO) network was demonstrated by a facile solvothermal route and vacuum filtration method. As binder‐free anodes for LIBs, sandwiched structure ZCO/rGO electrode synergistically realized high lithium storage capability and good cycling stability due to enhanced conductive skeleton, robust mechanical stability and high hierarchical porosity. The ZCO/rGO hybrid depicts a reversible discharge capacity of 908.7 mAh g−1 after 500 long‐term cycles at a current density of 500 mA g−1. In addition, the flexible electrode also shows the excellent rate capacity with an average capacity of 681.8 mAh g−1 even at a large current density of 6000 mA g−1. Flexible sandwich structured ZCO/rGO anode for LIBs was synthesized by a facile solvothermal route and vacuum filtration method. The ZCO/rGO hybrid depicts a reversible discharge capacity of 908.7 mAh g−1 after 500 long‐term cycles at a current density of 500 mA g−1. The results show great potential for the general and facile fabrication of transition metal oxides/graphene electrodes with long span life. [ABSTRACT FROM AUTHOR]
