Lithium hexafluorophosphate is an inorganic substance with the chemical formula LiPF6, white crystal or powder. It is easily soluble in water, but also soluble in low-concentration methanol, ethanol, acetone, carbonates and other organic solvents. It is the most important component of the electrolyte composition, accounting for about 43% of the total cost of the electrolyte. In the fluorine chemical industry, although traditional products have experienced a significant year-on-year decline, the demand for high-end products has maintained a strong momentum. In particular, the production and sales of lithium hexafluorophosphate continue to maintain a good momentum. With the continuous expansion of the new energy field in the future, lithium hexafluorophosphate is expected to usher in a continuous outbreak. In the future, other new lithium salts are expected to replace lithium hexafluorophosphate.
