Lithium Hexafluorophosphate

Lithium hexafluorophosphate is one of the most important components of electrolyte

Product characteristics

White crystal or powder, relative density 1.50, strong deliquescence; Easily soluble in water, but also soluble in low concentration methanol, ethanol, propanol, carbonate and other organic solvents. When exposed to air or heated, it decomposes rapidly due to the action of water vapor, releasing PF5 and producing white smoke.

Application description

It can be used as the electrolyte material of lithium-ion battery and is the most important component of electrolyte composition. Compared with other electrolyte lithium salts, it has the characteristics of high conductivity, good electrochemical stability, good compatibility with graphite negative electrode, effective passivation of aluminum foil and low relative cost.

Properties

White crystal or powder, relative density 1.50. Deliquescence is strong; It is easily soluble in water and also soluble in organic solvents such as low concentration methanol, ethanol, acetone and carbonate. Decompose when exposed to air or heated. When exposed to the air or heated, lithium hexafluorophosphate decomposes rapidly in the air due to the action of water vapor, releasing PF5 and producing white smoke. Lithium hexafluorophosphate is mainly used as electrolyte material for lithium ion battery. Lithium hexafluorophosphate electrolyte is mainly used in the manufacture of lithium ion batteries.
