摘要：

Porous structure LiFePO4 with pore size from 2 to 15 nm was successfully synthesized in mixed solvents system of glycol and water. By changing stirring time from 5 to 60 min, LiFePO4 morphologies were adjusted and percentage of porous LiFePO4 was higher and higher in sequence. Stirring time is the key cause of controlling morphologies of final products for its influence on diffusion rate of the initial formed particles of final products. Through adjusting this factor, products with specific morphologies and functions can be obtained. The morphologies and microstructures were observed by transmission electron microscopy (TEM), and the phase composition was verified by X-ray diffraction (XRD). This synthetic method provides a new route to obtain porous structure materials.
