Properties:
Lithium tetrafluoroborate (chemical formula: LiBF₄) is an inorganic compound that appears as a white crystalline powder at room temperature. It is readily soluble in water, acetonitrile, and polar solvents such as carbonates. It exhibits high thermal stability, with a melting point of approximately 293-300°C. However, it is prone to hygroscopic decomposition in humid air and therefore requires sealed storage in a dry environment. Furthermore, its density is 0.852 g/cm³, its aqueous solution is weakly acidic, and it demonstrates excellent ionic conductivity in electrochemical applications.
Application:
Lithium tetrafluoroborate is primarily used as a key electrolyte salt or additive in lithium-ion battery electrolytes, enhancing the ionic conductivity and stability of the electrolyte, and improving the battery’s high and low temperature performance and cycle life. Simultaneously, it is commonly used as a mild Lewis acid catalyst in organic synthesis, promoting reactions such as the Diels-Alder reaction, ethylene oxide ammonolysis, and intramolecular nitrogen-Micelle addition. Furthermore, this compound can be used in emerging energy fields such as the preparation of ionic liquids, electroplating electrolytes, and supercapacitors.
