Overview
LiPF6 combines high conductivity, good electrochemical stability and film-forming ability, making it the core lithium salt of commercial electrolytes. It is extremely moisture-sensitive and hydrolyzes to HF, so production, filling and storage all require a low-dew-point environment.
- Purity ≥ 99.9%
- HF ≤ 50 ppm, H₂O ≤ 20 ppm
- Low insolubles, compatible with high-nickel systems
