LiBNTFSI (Lithium Bis(nonafluorobutanesulfonyl)imide, or LiNNf2, >99.5%) Powder as Electrolyte Salt and Additive for Lithium-Ion Battery, 10-50 g/bottle, CLIBEALiBNTFSI

Lithium bis(nonafluorobutanesulfonyl)imide (LiBNTFSI or LiNNf_2) (CAS 119229-99-1) is an advanced, highly fluorinated imide-based lithium salt utilized as a specialty electrolyte additive or co-salt in high-performance lithium-ion and lithium-metal batteries.

The main features of the LiBNTFSI are: (1) High Anodic Stability Window: Withstands high operating voltages (> 4.5 V vs. Li/Li+), making it well-suited for high-voltage layered oxides (e.g., NMC811, NCA) and high-voltage lithium-metal configurations. (2) Enhanced Thermal & Hydrolytic Resilience: The dense perfluorinated carbon tails impart high thermal stability and superior resistance to chemical degradation compared to traditional conventional salts. (3) Advanced Electrolyte Customization: Frequently incorporated into specialized formulations—including ionic liquids, gel polymer electrolytes, and highly fluorinated localized high-concentration systems—to lower viscosity, widen operational temperature windows, and suppress flammability.
