Growth of FePO4 nanoparticles on graphene oxide sheets for synthesis of LiFePO4/graphene

FePO4 center dot xH(2)O/graphene oxide (FePO4 center dot xH(2)O/GO) composites were prepared by a facile chemical precipitation method. Using the as-prepared FePO4 center dot xH(2)O/GO and LiOH center dot H2O as precursors and followed by carbothermal reduction, LiFePO4/graphene composites were obtained. Scanning electron microscope (SEM) images indicated that the graphene had very good dispersity and uniformly attached to the LiFePO4 particles. The conductive framework of graphene improved the electrochemical properties of the composites. The composites deliver high initial discharge capacity of 163.4 mAh g(-1) as well as outstanding rate performance.
