Fayalite (a-Fe2SiO4)@C nanocomposites are prepared via a solid state reaction by controlling different calcinating temperature (600 °C 700 °C and 800 °C) under the flow of nitrogen gas. The typical α-Fe2SiO4 phase is detected in the fayalite@C nonocomposites calcinated at 700°C and 800 °C by XRD analysis. Little impurity is found in the fayalite@C nonocomposites calcinated at 700°C, while no impurity is found in the the fayalite@C nonocomposites calcinated at 800°C. The average particle size of the fayalite@C nanocomposites calcinated at 700°C is about 32 nm analysed from SEM images, which is obviously smaller than that of fayalite@C calcinated at 800°C. In addition, the fayalite@C nanocomposites calcinated at 700°C show the best electrochemical performance among the three samples.
