High-Rate LiFePO4 Electrode Material Synthesized by Chemical Grinding Method
A facile solid state method based chemical grinding method was applied to prepare high rate LiFePO4. SEM test results showed that the prepared LiFePO4 (CG-LiFePO4) is more fine and uniform than that of the crude LiFePO4 (C-LiFePO4) prepared by conventional solid state reaction method. Electrochemical measurement results indicated that CG-LiFePO4 exhibited much better high-rate characteristic than crude one which delivered a stable discharge capacity of 140 mAhg -1, 126 mAhg -1 at 0.5C rate and 2C rate respectively.
