Abstract

The spherical LiFePO4 with nano-size is expected as an important direction for LiFePO4 cathode materia1.With the method of liquid co-deposited-carbonthermal reduction,we prepared spherical LiFePO4 cathode material with nano-size and we put our emphasis on the effect of sintering time on the material.By XRD,SEM,TEM and charge & discharge analysis,we found the sample sintered at 550 ℃ for 10 hours showed the best electrochemical properties and good degree of sphericity,with the size of 40~100 nm.
