Multilayered graphene/LiFePO4 composite materials were prepared by an ultrasonic-assisted rheological phase method and carbothermal reduction in an inert atmosphere.The crystal structure and the electrochemical performances were characterized by XRD,SEM and electrochemical performance testing.The testing results of multilayered graphene/LiFePO4 composite materials show more excellent electrochemical performances compared to LiFePO4 produced in the same way.Its discharge capacity at 0.2C as a lithium secondary battery reaches to 152mAh·g-1,and the materials show excellent high rate performance and cycling performance.
