Lithium hexafluorophosphate (LiPF6) is used as a lithium-ion battery electrolyte and is mainly used in lithium-ion power batteries, lithium-ion energy storage batteries and other daily batteries. It is also an irreplaceable lithium-ion battery electrolyte in the near and medium term.
Lithium hexafluorophosphate is a white crystal or powder with a relative density of 1.50. Strong deliquescence; easily soluble in water, but also soluble in low-concentration methanol, ethanol, acetone, carbonates and other organic solvents. Decompose when exposed to air or heated. When exposed to air or heated, lithium hexafluorophosphate quickly decomposes in the air due to the action of water vapor, releasing PF5 and producing white smoke.
Proportion of raw materials for the production of lithium hexafluorophosphate (LiPF6):
Lithium fluoride:0.18
Anhydrous hydrogen fluoride:2.4
Phosphorus pentachloride: 1.68
Liquid chlorine: 2.15
