摘　　要：合成了一种氟化磷酸酯,通过核磁共振(NMR)分析结构,研究合成的氟化磷酸酯对锂/氟化碳电池电化学性能的影响。在合成的氟化磷酸酯电解液体系中,常温0.02 C放电比容量为816 mAh/g,2.00 C放电比容量衰减至435 mAh/g;高温55℃时,0.02 C放电比容量为869 mAh/g,2.00 C放电仍可保持在758 mAh/g。The fluorination phosphate ester was synthesized, the structure was analyzed by nuclear magnetic resonance （NMR）. The effect of synthesized fluorination phosphate ester on electrochemical performance of Li/CFx battery was studied. In the synthesized fluorination phosphate ester electrolyte system, the 0. 02 C specific discharge capacity was 816 mAh/g at normal temperature, the 2. 00 C specific discharge capacity was decreased to 435 mAh/g ; the 0. 02 C specific discharge capacity was 869 mAh/g at high temperature（55 ℃） ,kept at 758 mAh/g when discharged with 2. 00℃.
