| Abstract: | FePO4·xH2O/graphene oxide (FePO4·xH2O/GO) composites were prepared by a facile chemical precipitation method. Using the as-prepared FePO4·xH2O/GO and LiOH·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. |
