Abstract�� 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.
