Lithium hexafluorophosphate (LiPF₆, CAS: 21324-40-3) is a key electrolyte salt widely used in the new energy lithium-ion battery industry. This compound is a white crystalline powder with the molecular formula LiPF₆. It is highly soluble in carbonate-based organic solvents such as EC, DMC, and DEC, offering excellent ionic conductivity and electrochemical stability. Since it can decompose in air to generate HF, it must be stored under inert atmosphere.
As the core component of lithium battery electrolyte, Lithium hexafluorophosphate provides high ionic conductivity and forms a stable SEI film on the electrode surface, enhancing cycle life and safety. It also features a wide electrochemical stability window, making it suitable for high-voltage battery systems. Thanks to these advantages, LiPF₆ is widely applied in power batteries, electric vehicle batteries, energy storage systems, and consumer electronics, as well as in supercapacitors and other electrochemical storage applications.
With the rapid growth of the new energy industry, the demand for high-purity Lithium hexafluorophosphate (LiPF₆) continues to rise. As a critical new energy battery raw material, it plays an irreplaceable role in lithium battery electrolyte formulations. High-quality LiPF₆ not only improves energy density but also extends service life, providing stable and reliable performance for electric vehicles, energy storage stations, and electronic devices.
