摘　　要：以Na2CO3、TiO2和NH4H2PO4为原料,采用球磨和高温烧结的方法合成了NaTi2(PO4)3材料,研究发现烧结温度对于材料的生成和结晶性具有显著影响,烧结温度越高,所合成的NaTi2(PO4)3相越纯,得到的产率也越高。测试了制备的NaTi2(PO4)3材料作为钠离子电池负极材料的电化学性能,其比容量0.1C倍率下可达到107mAh/g。In this paper, NaTi2(PO4)3 materials were synthesized through ball milling and high-temperature calcine process, using Na2CO3, TiO2 and NH4H2PO4 as raw materials. It was found that caline temperature has a significant impact on the formation and crystallization of materials. The higher caline temperature is, the more pure phase is synthesized and the higher yield is obtained. The electrochemical performance of the prepared NaTi2(PO4)3 material as the anode material of sodium ion battery was tested, and its specific capacity reached 107 mAh/g at 0.1C.
