Lithium tetrafluoroborate

Lithium tetrafluoroborate (LiBF₄) is an inorganic compound that is commonly used as an electrolyte salt in lithium-ion batteries and other electrochemical applications. It consists of lithium cations (Li⁺) and tetrafluoroborate anions (BF₄⁻). The tetrafluoroborate anion is characterized by its stable tetrahedral structure, where a boron atom is surrounded by four fluorine atoms.
