Application

Sodium Difluorophosphate serves as a critical electrolyte additive in lithium-ion batteries, improving cycle life and high-temperature performance by stabilizing the solid-electrolyte interphase (SEI) layer. It is also investigated for corrosion inhibition in metal surface treatments due to its ability to form protective fluoride-containing films. Additionally, researchers explore its potential in specialty ceramics and flame retardants owing to its thermal stability and phosphorus-fluorine chemistry.
