| 摘 要： | 为同时提高电极材料的电化学性能和振实密度,通过以廉价的Fe(NO_3)_3·9H_2O为铁源,以十二烷基硫酸钠为表面活性剂,在100℃水浴条件下反应24 h,合成了自组装的3D"微纳结构"FePO_4·2H_2O纳米材料。对其进行XRD、SEM分析,结果显示该材料为纯的FePO_4·2H_2O,其形貌为由长100 nm、厚50 nm的纳米片自组装而成直径约2μm的近球状结构。该结构有利于综合锂离子电池正极材料中纳米材料导电性好、微米材料振实密度高的优点,为电极材料的研发提供有利借鉴。

| Abstract: | To simultaneous enhance the electrical chemical performance and the tap density,the self-assembled 3D "micro-nano-structure" FePO4·2H2O was synthesized by using the cheap Fe (NO3)3·9H2O as iron source and the lauryl sodium sulfate as surfactant,under reacting at 100 ℃ for 24 h via a water bath method.The results of XRD and SEM show the material are pure and like a ball with a diameter about 2 iμm which composes of nano-plates with the length of about 100 nm and thickness of 50 nm.The structure could combine the advantages of good electrical conductivity of nano-materials and high tap density of micro-materials,which will be useful to the research of electrodes. |
