Synthesis of lithium manganese phosphate nanoparticle and its properties

The LiMnPO4 fine particles were synthesized by polyol method. To optimize the synthesis conditions of the LiMnPO4 compounds, we have prepared the LiMnPO4 compound with different processing conditions. The samples were characterized by X-ray diffraction, scanning electron microscope observation and infrared spectroscope study. The particle size of the as-prepared samples are very small than the sample calcined at 500 degrees C for 3 h in Ar. The electrochemical properties of the cathodes were studied by galvanostatic method. All the samples exhibit a sloping line of the voltage profile, which is the characteristic of the nanoparticles.
