The spherical mesoporous iron phosphate (P-FP) were prepared by liquid phase crystallization method, and then Carbon-coated lithium iron phosphate was synthesized by high temperature solid phase method using the spherical mesoporous iron phosphate as precursors (P-LFP/C) or using the non-mesoporous iron phosphate as precursors (LFP/C). The P-LFP/C were characterized by X-Ray-Diffraction, Scanning-Electron-Microscope, Fourier-Transform Infrared Spectrometer and electrochemical tests. The results show that the initial discharge capacity of the P-LFP/C at 0.1 C increase by 27.10%, reaching 159.29 mAh g(-1), and the electrode charge transfer resistance reduce by 88.16%, just 48.320 Omega. compare with the LFP/C. And the P-LFP/C exhibited better discharge capacity at initial 151.78 and 112.11 mAh g(-1) at 0.2 C and 5 C rate, respectively. It is beneficial to the lithium ion escaped and embed in the process of charging and discharging and enhanced the electronic conductivity and rate performance of the cathode materials.
