Popis:	LiFePO4/C composite is one of ways to surmount the lower electrical conductivity of LiFePO4. In this paper, we suggest a new type of LiFePO4/C composite in which amorphous nano-carbon webs are wrapping and connecting LiFePO4 particles. This type of composite was obtained by adapting a new liquid-based powder preparation method, that is, all raw materials (LiFePO4 and carbon precursor materials) were dissolved in liquid and solidified. This composite was very effective in enhancing the electrochemical properties such as capacity and rate capability. Even as high as at 400 m Ag−1 current density, a capacity of about 105 m Ahg−1 was obtained at 25 °C.
