摘要
The worm-shaped nano-Li2FeSiO4/C was obtained from calcination of the precursor synthesized by a microemulsion method under mild conditions. The obtained sample was characterized by X-ray diffraction (XRD) and field emission scanning electron microscope (FESEM). The electrochemical experiments reveal that the worm-shaped nano-Li2FeSiO4/C composite sintered at 700 degrees C for 9 h has good cycle stability and rate capability with an initial discharge capacity of 140.1, 139, and 94 mAh/g at C/16, C/8 and 1C rate, respectively and the capacity retention ratios is 96.4%, 81.2% and 73.5% at the twentieth cycle, respectively.
