Lithium hexafluorophosphate (LiPF₆)(CAT: M009186) is a white crystalline salt widely used as an essential electrolyte component in lithium-ion batteries. It provides high ionic conductivity and stability in organic carbonate solvents, making it ideal for high-performance energy storage systems. LiPF₆ plays a critical role in forming a stable solid electrolyte interphase (SEI) on electrode surfaces, which enhances battery efficiency and lifespan. Despite its moisture sensitivity and thermal decomposition risk, it remains the industry standard due to its balance of electrochemical performance and solubility. Beyond batteries, it is also used in electrochemical research and specialty chemical synthesis involving fluorinated lithium salts.
