What is Lithium hexafluorophosphate?
Lithium hexafluorophosphate (CAS 21324-40-3), commonly referenced as LiPF6, is the dominant electrolyte salt in commercial lithium-ion battery manufacturing.
Where is Lithium hexafluorophosphate used?
- Electric vehicles, consumer electronics and grid-scale energy storage: primary electrolyte solute in lithium-ion cells
- Electrolyte solutions: dissolved in carbonate solvent blends
- Solid-state research: electrolyte development
- Next-generation lithium battery research relies on this material for testing and development.
Good to know: Strict controls on moisture, HF content and metallic impurities; the material is humidity-sensitive, so moisture-controlled packaging sealed under inert atmosphere and proper handling during storage and transit are needed.
Commercial specifications
- Battery-grade specification
- Purity typically 99.9% or higher
- Electrolytes formulated at specific concentrations for capacity retention and rate capability
