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溶剂、溶液法和乙腈溶剂的LiPF6制备工艺的现状及优缺点,认为以乙腈做溶剂的工艺法可能是今后工艺开发的最佳方向。
Lithium hexafluorophosphate（LiPF6） is used as electrolyte in lithium battry and choose solvent becomes a key factor to make highly pure LiPF6.The article discusses the present advantages and disadvantages of the preparation techniques of LiPF6 with hydrogen fluoride solvents,olution method and ather anhydrous solvents used as solvents.At last the acetonitrile is proposed as the most suitable solvent in the future.
