With Fe(NO₃)₃·9H₂O,LiNO₃,NH₄ H₂PO₄ and sucrose as raw materials, LiFePO₄/C was synthesized by using supercritical carbon dioxide at 50℃ for 24 h,and then being annealed at 350℃ and 600℃. The particle size of synthesized LiFePO₄/C is in the range of 0.5~1.0 μm. For the electrochemical performance of LiFePO₄/C as the cathode material of lithium ion battery,the initial discharge capacity is 156.6 mA·h/g,and there is no obvious capacity fading after 50 cycles.
