Li2FeSiO4/C composites were one-step synthesized under hydrothermal conditions at 200 A degrees C for 72 h using glucose as carbon source. By adjusting the quantity of added glucose, we obtained varied Li2FeSiO4/C composites with different size and morphology. A series of electrochemical tests demonstrate that the Li2FeSiO4/C nanoparticles with diameters about 20 nm have higher discharge capacity, and slower capacity fading in comparison with Li2FeSiO4 and other Li2FeSiO4/C composites. Li2FeSiO4/C nanoparticles deliver a discharge capacity of 136 mAh g(-1) at 0.2 C, and after 100 cycles, the discharge capacity remains 96.1%. Furthermore, Li2FeSiO4/C nanoparticles also exhibit an excellent rate capability with a capacity of about 80 mAh g(-1) at 10 C.
