General description

Lithium tetrafluoroborate is a class of electrolytic materials that can be used in the fabrication of lithium-ion batteries. Lithium-ion batteries consist of anode, cathode, and electrolyte with a charge-discharge cycle. These materials enable the formation of greener and sustainable batteries for electrical energy storage.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

LiBF4 is majorly used as an electrolyte with good ionic conductivity. It facilitates the formation of an electrolytic solution or a liquid electrolyte, which can be used in the fabrication of lithium-ion batteries and solid-state electrochemical displays.
Used recently in the development of a solid composite electrolyte for lithium batteries.
