A one-step microwave-assisted pyrolysis of ionic liquid process is developed to synthesize carboncoated LiFePO 4 by using the ionic liquid [BMIm]N(CN) 2 as a carbon source. A thin layer of uniform and nanoscaled carbon¯lm is formed on the LiFePO 4 particles surface with a strong interface. The electrochemical properties of LiFePO 4 are improved due to the carbon coating which increases the electronic conductivity of LiFePO 4 . The results indicate that the microwaveassisted pyrolysis of ionic liquid process is a rapid and e±cient method to prepare carbon-coated LiFePO 4 material and other carbon-coated electrode materials.
