Product Description

Lithium salt electrolytes are a crucial component of lithium battery electrolytes. Common lithium salts include lithium hexafluorophosphate(LiPF6)、lithium hexafluoroarsenate(LiAsF6)、lithium perchlorate(LiClO4)、lithium tetrafluoroborate(LiBF4)、lithium bis(trifluoromethanesulfonyl)imide(LiN(CF3SO2)2), and others. Compared to electrolytes such as LiBF4, LiAsF6, and LiClO4, LiPF6 exhibits significant advantages in solubility in organic solvents, conductivity, safety, and environmental friendliness. It is a lithium salt with excellent performance and a high degree of commercialization, making it the widely used lithium salt electrolyte. In the foreseeable future, no other material can replace the role of lithium hexafluorophosphate in lithium batteries.

Our company is one of the earliest domestic enterprises to develop lithium hexafluorophosphate preparation technology. During the research and development process, we received support from national and local science and technology funds. Our process differs from the phosphorus pentachloride method used by most production enterprises; it is the more challenging fluorine gas method. Leveraging our company's advantage in electrolytic fluorine production technology, we directly prepare high-purity phosphorus pentafluoride (PF5) through the reaction of fluorine gas with phosphorus. Therefore, the final product, LiPF6, is free of impurities such as chloride ions, achieving higher purity and better crystallization, making it a high-quality product in lithium battery electrolytes.
