锂电池电解质     六氟磷酸锂                                                                                                     

六氟磷酸锂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LiBF4LiAsF6LiClO4

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具有优势,是目前应用范围

广的锂盐。

Lithium battery electrolyte    Lithium hexafluorophosphate                                                      

As one of the most important component of electrolyte,the cost of LiPFaccounts for about 43% to the total

cost of electrolyte. Compared with other electrolyte such as LiBF4, LiAsF6, LiClOetc., LiPFis the most wildly

used Li salt electrolyte, because of the advantages in conductivity, safety, solubility in organic solvent and eco-

friendliness.

As an electrolyte of lithium ion battery, lithium hexafluorophosphate is mainly used in lithium ion power battery, lithium ion energy storage battery and other batteries.

  

1. Lithium hexafluorophosphate is packaged under closed and dry conditions.

2. Products with a net content of no more than 10Kg are packaged in a corrosion resistant bottle or vacuum-packed in an aluminum bag.

3. Products with a net content of not less than 25Kg are packaged in stainless steel barrel, the pressure-resistant capacity of the stainless steel barrel is greater than 0.6MPa, inert gas should be filled with the barrel (air pressure not less than 30KPa), and the barrel should be covered with protective cover.
