Lithium Difluoroxalate Borate (LiDFOB) is a functional lithium salt used primarily as an electrolyte additive in lithium‑ion battery systems. Identified by CAS 409071‑16‑8, it combines fluorine‑containing borate chemistry with oxalate coordination, enabling improved interfacial stability and film‑forming behavior on electrode surfaces. These characteristics support its application in advanced battery electrolyte formulations, particularly where enhanced cycle life and thermal stability are required.
This product is supplied for battery material applications with controlled purity, supports customized specifications, and is delivered with complete MSDS, TDS, COA documentation for industrial use.

FAQ - Technical & Supply Chain
-
Q:
How is Lithium Difluoroxalate Borate different from LiBOB in battery electrolytes?
A: LiDFOB contains fluorine atoms in the borate structure, which can enhance interfacial film formation and stability compared with LiBOB, leading to different electrochemical behavior in lithium‑ion battery systems. -
Q:
What role does LiDFOB play in electrolyte formulations?
A: LiDFOB is typically used as an electrolyte additive rather than a primary lithium salt, where it contributes to electrode surface protection and improved cycling performance.
