Lithium Hexafluorophosphate
六氟磷酸鋰（LiPF6）為白色結晶或粉末，相對密度為1.5。易溶于水，易溶于乙腈、碳酸乙烯酯（EC）、碳酸丙烯酯（PC）、碳酸二甲酯（DMC）、四氫呋喃（THF）、乙二醇二甲醚（DME）等有機溶劑。
LiPF6是電解液成分中重要的組成部分，約占到電解液總成本的43%。與LiBF4、LiAsF6、LiClO4等電解質相比，LiPF6在有機溶劑中的溶解度、電導率、安全性和環保性方面最具優勢，是目前應用范圍最廣的鋰鹽。
Lithium hexafluorophosphate (LiPF6) is a white crystal or powder, the relative density of 1.5. soluble in water, soluble in Acetonitrile,Ethylene carbonate (EC) ,Propylene carbonate(PC) , Dimethyl carbonate(DMC), Tetrahydrofuran (THF), 1,2-Dimethoxyethane (DME) and other organic solvents.
LiPF6 is an important component of electrolyte, accounting for about 43% of the total cost of electrolyte. Compared with LiBF4, LiAsF6, LiClO4 and other electrolytes, LiPF6 has advantages in solubility, conductivity, safety and environmental protection in organic solvents, and is the most widely used lithium salt at present.
