Abstract:
Porous structure LiMnPO4 with pore size from 4 to 9 nm was successfully synthesized in mixed solvents. By changing ratios of glycerol to distilled water and stirring time, LiMnPO4 morphologies were adjusted. Shuttles with different sizes and porous structure of LiMnPO4 were formed in sequence. Ratio of glycerol to distilled water influences the solubility of LiMnPO4 and solutions viscosity. This factor and stirring time are both causes influencing the nucleation rate and diffusion rate of the initial formed particles of final products. Through adjusting these factors, chemicals with specific morphology can be obtained. The phase composition was investigated by X-ray diffraction (XRD), and the microstructure was verified by transmission electron microscopy (TEM). This synthetic method provides us a new idea to obtain new structure materials.
