Abstract: A simple template method was used to fabricate porous graphene framework (pG), and a pomegranate-like zinc vanadate (Zn3V3O8) nanospheres were coated in the porous graphene nanosheets to form the unique structure of zinc vanadate/porous graphene (Zn3V3O8/pG) nanocomposites. As an anode material for lithium ion batteries (LIBs), the Zn3V3O8/pG show good lithium storage performance and deliver a reversible capacity of 586 mAh g-1 at 1000 mA g-1 after 200 cycles. The superior electrochemical performance of Zn3V3O8/pG nanocomposites can be attributed to the unique porous network carbon structure, which provides buffer space for the volume change of Zn3V3O8 nanospheres during charge and discharge cycles, and the synergistic effects between pomegranate-like Zn3V3O8 nanospheres and porous graphene network.
