The Uses of Lithium tetrafluoroborate

Lithium tetrafluoroborate is a mild Lewis acid for Diels-Alder reactions. Catalyst for mild and efficient aminolysis of oxiranes. It is a reagent used in the preparation of rechargeable lithium-ion batteries.

The Uses of Lithium tetrafluoroborate

Catalyst in organic synthesis; electrolyte for lithium ion batteries.

The Uses of Lithium tetrafluoroborate

Lithium tetrafluoroborate (LiBF₄) finds application as electrolyte material in lithium ion batteries (LIBs). However, the presence of trace amount of water in LiBF₄ causes its hydrolysis which leads to HF generation and destruction of the battery electrodes. Our LiBF₄ contains < 100 ppm of water and is well suited for applications in LIBs.

Purification Methods

Dissolve it in THF just below its solubility, filter from insoluble material and evaporate it to dryness in a vacuum below 50o. Wash the residue with dry Et2O, and pass dry N2 gas over the solid and finally heat it in an oven at 80-90o. Its solubility in Et2O is 1.3g in 100mL at 25o; in THF it is 71g in 100mL at 25o. It is hygroscopic and is an IRRITANT. [Elliott et al. J Am Chem Soc 74 5211 1952, 75 1753 1953.]
