| 摘 要： | 以自制的磷酸铁作为铁源和磷源,用高温自生压力法（即RAPET法）合成了LiFe-PO4/C复合材料,分别比较了以葡萄糖、蔗糖或柠檬酸为碳源和以碳酸锂或氢氧化锂为锂源所得LiFePO4/C复合材料电化学性能的影响。利用X射线衍射（XRD）、循环伏安（CV）、交流阻抗（EIS）和充放电测试等方法,分别对样品的晶型和电化学性能等进行了表征和分析。结果表明：以柠檬酸为碳源、碳酸锂为锂源制备的LiFePO4/C复合材料电化学性能更优异,首次放电比容量达到166.1mAh/g。

| Abstract: | Olivine-type LiFePO4/Carbon composites were synthesized by the RAPET method using FePO4 as iron and phosphate sources,glucose,sucrose or citrate as carbon sources and LiOH or Li2CO3 as lithium sources,respectively.The effects of carbon and lithium precursors on the electrochemical performance of the derived LiFePO4/Carbon composites were investigated.XRD,CV,EIS and charge/discharge tests showed that all the LiFePO4/Carbon composites have good crystallites and excellent electrochemical performance.LiFePO4/Carbon composite synthesized using citrate as carbon source and Li2CO3 as lithium source shows the excellent performance with discharge capacity of 166.1 mAh /g at 0.1 C. |
