General description

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.
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

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
Our battery grade lithium difluorooxalatoborate (LiODFB) is a thermally stable salt and an electrolytic additive for lithium-ion batteries. LIODFB facilitates the formation of stable solid electrolyte interphase (SEI) on the negative electrode, which enhances the cycling efficiency and safety of the battery. Moreover, LiODFB is capable of stabilizing the solid electrolyte interface (SEI) on the surface of lithium metal, graphite, and silicon anode materials, substantially enhances the cyclic performance, capacity and power retention of the electrochemical cells.[5][6][7] In particular, LiODFB is suitable for high-performance Li-ion batteries operating at low temperatures and fast charge and discharge rates.

Features and Benefits

LiODFB improves the efficiency and safety of lithium-ion batteries, allowing them to deliver better performance over a longer time.
✔ Increases battery life
✔ Stabilizes SEI layer
✔ Suitable for fast charging and low temperatures
