一出一步舞合成方法被用来综合由 Fe, Li_3 PO_4,和 FePO_4 粉末, XRD 和 TEMmeasurements 的 stoichiometric 混合揭示了的直接的球 milling 的 Olivline LiFePO_4 粉末同样准备的 LiFePO_4 粉末让同类的橄榄石结构和一件制服缩放 ca 的分发。50 nm。把材料基于这, LiFePO_4/C 合成被准备并且为 Li 离子电池的阴极材料使用了。费用分泌物实验证明 LiFePO_4/C 合成材料在 1 C 在 0.1 C 和 95 mAh/g 的一个相当高率的能力有 132 mAh/g 的一个高能力。这个新球工厂方法可以为准备这块类型花费有效地并且在大体积的材料提供一条完全绿的合成线路。
A one-step synthetic method was used to synthesize Olivline LiFePO4 powders by direct ball milling the stoichiometric mixture of Fe, Li3PO4 , and FePO4 powders. XRD and TEM measurements revealed that the as-prepared LiFePO4 powder have a homogeneous Olivine structure and a uniform size distribution of ca. 50 nm. Based on this material, a LiFePO4/C composite was prepared and used for the cathode material of Li-ion batteries. The charge-discharge experiments demonstrated that the LiFePO4/C composite material has a high capacity of 132 mAh/g at 0.1 C and a quite highrate capability of 95 mAh/g at 1 C. This new ball-milling method may provide a completely green synthetic route for preparing the materials of this type cost-effectively and in large volume.
