英文摘要high quality graphene sheets were prepared from graphite powder through oxidation followed by rapid thermal expansion in nitrogen atmosphere. the preparation process was systematically investigated by x-ray diffraction (xrd), fourier transform infrared spectroscopy (ftir), raman spectroscopy and brunauer-emmett-teller (bet) measurements. the morphology and structure of graphene sheets were characterized by scanning electron microscope (sem) and high-resolution transmission electron microscopy (hrtem). the electrochemical performances were evaluated in coin-type cells versus metallic lithium. it is found that the graphene sheets possess a curled morphology consisting of a thin wrinkled paper-like structure, fewer layers (similar to 4 layers) and large specific surface area (492.5 m(2) g(-1)). the first reversible specific capacity of the prepared graphene sheets was as high as 1264 ma h g(-1) at a current density of 100 ma g(-1). even at a high current density of 500 ma g(-1), the reversible specific capacity remained at 718 ma h g(-1). after 40 cycles, the reversible capacity was still kept at 848 ma h g(-1) at the current density of 100 ma g(-1). these results indicate that the prepared high quality graphene sheets possess excellent electrochemical performances for lithium storage.
