A New Method for the Synthesis of LiFePO4/C
Abstract:
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.
