摘　　要：锂离子电池一般采用LiPF6作为其电解质,合成高纯度LiPF6的关键是溶剂的选择,本文分别介绍了目前以无水氟化氢、醚和其它非水溶剂为溶剂的LiPF6制备工艺的现状及优缺点,认为以醚做溶剂的工艺法可能是今后工艺开发的最佳方向。Lithium hexafluorophosphate(LiPF_6) is used as electrolyte in lithium battery and choosing solvent becomes a key factor to make highly pure LiPF_6.The article discusses the present advantages and disadvantages of the preparation techniques of LiPF_6 with hydrogen fluoride,ether,and other anhydrous solvents used as solvents.At last the ether is proposed as the most suitable solvent in the future.
