A new method to synthesize olivine phosphate nanoparticles

摘要：

Well-crystalline LiFePO4 nanoparticles were prepared by the polyol process without post heat treatments. X-ray diffraction showed an orthorhombic phase without any discernible existence of impurities. The particles showed highly crystalline nature of rod and plate like morphologies with an average size of 300nm. The initial discharge curve of LiFePO4 showed a capacity of 168mAhg-1 at a 0.1C rate in the voltage range of 2.5-4V with good retention at high rate current densities. This amounts to a utilization efficiency of 98％, with excellent reversibility in extended cycles. LiFePO4 nano-particle showed a high capacity of 102mAhg-1 at a high rate of 6.4C.
