Abstract

Both electron transfer and Li-ion diffusion are the key factors limiting rapid lithium storage in anisotropic LiFePO₄ electrode materials. In this work, graphenes were used to in situ anchor LiFePO₄ nanoplatelets (LFP NPs) with orientated (010) facets to prepare a unique LiFePO₄-graphene composite (LFP@GNs). Electron microscope images revealed the nanoplatelet morphology of LiFePO₄ crystals as well as the graphene crossed-linked structure of LFP@GNs. X-ray diffraction and high-resolution transmission electron microscopy results demonstrated the orientated growth of LFP nanoplatelets along the ac-facet. LFP@GNs exhibited a superior rate capability with a discharge capacity of 126 mAh g^-1 at 20C, as well as an excellent cycling stability without capacity fading after 600 cycles at 10C.
