采用多元醇法合成了LiMnPO4微粒。为了优化LiMnPO4化合物的合成条件，我们采用不同的工艺条件制备了LiMnPO4化合物。采用X射线衍射、扫描电镜和红外光谱对样品进行了表征。所制备的样品的颗粒尺寸比在500 ° C下在Ar中焙烧3小时的样品非常小。用恒电流法研究了阴极的电化学性能。所有样品都表现出电压曲线的斜线，这是纳米颗粒的特征。
The LiMnPO4fine particles were synthesized by polyol method. To optimize the synthesis conditions of the LiMnPO4compounds, we have prepared the LiMnPO4compound 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∘C for 3h 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.
