Synthesis of LiMnPO4 Porous Plates in Mixed Solvents System

0.6 to 7.5 mu m LiMnPO4 porous plates with pore sizes from 100 to 150 nm were successfully synthesized in mixed solvents of ethylene glycol and distilled water. By changing stirring time, different morphologies of LiMnPO4 were prepared. Porous plates with the percentages of more than 70%, more than 50% and 25% porous ones were formed in sequence. The according rest parts were particles, less than 40% solid plates and 25% solid ones, respectively. Stirring time is the key cause influencing the nucleation rate and diffusion rate of the initial formed growth units of LiMnPO4. Through adjusting the factor, chemicals with specific morphology can be obtained in mixed solvents. The phase composition and microstructure were investigated by X-ray diffraction (XRD) and transmission electron microscopy (TEM), respectively. This synthetic route provides us a new idea to prepare new structure materials.
