六氟磷酸锂

Lithium Hexafluorophosphate

六氟磷酸锂（LiPF₆）为白色结晶或粉末，相对密度为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）、四氢呋喃（THF）、乙二醇二甲醚（DME）等有机溶剂。
LiPF₆是电解液成分中重要的组成部分，约占到电解液总成本的43%。与LiBF₄、LiAsF₆、LiClO₄等电解质相比，LiPF₆在有机溶剂中的溶解度、电导率、安全性和环保性方面最具优势，是目前应用范围最广的锂盐。
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.

包装、贮存 Packaging and storage

六氟磷酸锂在密闭、干燥条件下进行包装。净含量不大于10Kg的产品采用耐腐瓶包装，外用铝塑膜袋抽真空包装。净含量不小于25kg的产品采用不锈钢桶包装，不锈钢桶应耐压能力大于0.6MPa，内充惰性气体（气压不小于30kPa），加盖防护盖。
Lithium hexafluorophosphate is packed under closed and dry conditions. Products with a net content of less than 10Kg are packed in corrosion-resistant bottles, then vacuum packaging with Al-laminated film. Products with a net content of at least 25kg are packed in stainless steel barrels, the stainless steel barrel should have a pressure-resistant capacity of more than 0.6mpa, be filled with inert gas (air pressure not less than 30kPa), and be covered with a protective cover.
