General description

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.
Lithium difluoro(oxalato)borate (LIODFB) 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.

Application

LiODFB is used as a thermally stable novel salt and an electrolytic additive for lithium-ion batteries. It facilitates the formation of stable solid electrolyte interphase (SEI) on the negative electrode during the fabrication of the cell. It substantially enhances the cyclic performance, capacity and power retention of the electrochemical system.
Lithium difluorooxalatoborate (LIODFB) is a salt for high-performance Li-ion batteries with improved cycle life; power capability; low temperature and high rate performance of the battery. It has the advantages of both lithium bis(oxalato)borate (LiBOB) and LiBF4. LIODFB also stabilizes the solid electrolyte interface (SEI) on the surface of a graphite anode and is also used as an additive to improve the cycling efficiency and capacity retention of cells
