中文摘要：

通过“控制结晶”一碳热还原工艺合成出了球形LiFePO4／C材料。通过XRD、SEM、比表面及电化学性能测试等分析手段表明，通过调整控制结晶工艺参数，可以对产品颗粒粒径进行有效调控；合成出的LiFePO4／C材料呈类球形，具有较好的流动性和较高的堆积密度。比较了不同粒径材料的性能，发现平均粒径在5μzm时材料具有相对最好的综合性能。将该材料与目前市场上的几个优质产品进行了横向测评，以该材料制作出的电池具有更优异的电化学性能，特别是在高倍率下的电化学性能。

英文摘要：

Spherical LiFePO4/C material was synthesized by the controlled crystallization-carbon thermal reduction process. XRD,XRD,SEM,specific surface testing and the determination of the electrochemical properties showed that the particle size of product can be regulated and controlled effectivly by adjusting the control parameters of the crystallization process. The synthesized particles were spherical,with better flowability and higher tap density. Comparing the performance of different particle size of material,we found that the LiFePO4/C with an average particle size of 5μm had relatively better comprehensive performance. The materials and several high quality products on the market at present were evaluated hori- zontally. The electrochemical properties of the batteries assembled by this material were superior to the other materials, es- pecially the electrochemical performance at high rates.
