英文摘要	The first kind of mesoporous Fe2SiO4/C nanocomposites (MFS-1) were synthesized from the nano-SiO2 with a surface area of 137 m(2).g(-1) and the second kind of mesoporous Fe2SiO4/C nanocomposites (MFS-2) were prepared from the nano-SiO2 with a surface of 325 m(2).g(-1). XRD results indicate that alpha-Fe2SiO4 crystal phase appear in the two samples. SEM proves that the particle size of MFS-2 (30-40 nm) is smaller than that of MFS-1 (40-60 nm). TEM further proves Fe2SiO4 nanoparticles are homogeneously dispersed in the carbon networking of MFS-2. Pore structure analysis reveals that the specific surface area of MFS-2 (136 m(2).g(-1)) is evidently larger than that of MFS-1 (116 m(2).g(-1)), revealing the pore properties of mesoporous Fe2SiO4/C nanocomposites can be well controlled by using silica with different surface area. The above characters make MFS-2 exhibit a high initial reversible capacity of 667 mAh.g(-1) at 0.1 C, excellent rate capability (282 mAh.g(-1) at 10 C) and improved cycling stability (606 mAh.g(-1) at 1 C after 100 cycles).
