Effect of Iron Source and Temperature on Charge/Discharge Performance of LiFePO4

摘要：

　　LiFePO4 compound has been paid considerable attention as a promising positive electrode material.In this work,LiFePO4 compound was synthesized by the solid carbon thermal reduction reactions,where Fe2O3,Fe(OH)3 and FeSO4 is used as the iron resource respectively.All the synthesized products are pure phases except that using FeSO4 as the iron resource.The SEM images show porous morphologies,but different iron resource samples show different degree of pore ratio.According to the results of charge/discharge curves,capacity of the sample prepared by Fe(OH)3 as the iron resource shows superior to those of other samples.The result is attributed to more pores in the sample,which is benefit to electrolyte penetrating,short Li-ion diffusion distance.
