LiFSI (LITHIUM BIS(FLUOROSULFONYL)IMIDE) ELECTROLYTE SALT

HIGH PURITY BATTERY GRADE

Product Overview

This ultra-high purity LiFSI Powder, chemically designated as Lithium Bis(fluorosulfonyl)imide (CAS No. 171611-11-3), serves as a premium high conductivity electrolyte salt and indispensable low temperature battery additive. Specifically engineered to bypass the structural limitations of conventional salts, LiFSI significantly lowers electrolyte viscosity, drastically enhances ionic mobility, and inhibits low-temperature crystallization. Verified through rigorous analytical testing including ICP-OES and Karl Fischer titration, this white crystalline compound exhibits minimized trace metal parameters and exceptionally low moisture volatility. It is ideal for researchers optimizing high-rate performance, sub-zero cycling metrics, and long-term chemical durability in next-generation lithium battery configurations.

Key Features & Advantages

Superior Conductivity Elevation: Yields exceptional ion transfer rates compared to standard baseline lithium salts, optimizing power density profiles.
Outstanding Sub-Zero Performance: Suppresses electrolyte phase crystallization thresholds to maintain stable discharge capacity under cold environmental conditions.
Aluminum Foil Corrosion Suppression: High-purity structural balancing suppresses standard oxidative pitting on current collector surfaces at elevated operating potentials.
Robust Thermal Interface Stability: Formulates a smooth, integrated passivation interface that limits organic gas generation and cell volume expansion during long cycles.

APPLICATION SCOPE: Highly recommended for formulating low-temperature and fast-charging lithium-ion battery electrolytes, polymer gel testing matrix variants, extreme high-rate electrochemical systems, and functional salt prototyping workflows.

PACKAGING: Sealed tightly inside specialized inert containers wrapped in multi-layer protective moisture-barrier configurations under specialized oxygen-free conditions. Standard unit specification is 250g/bottle or tailored quantities upon direct contract specification.

IMPORTANT NOTICE: Lithium Bis(fluorosulfonyl)imide (LiFSI) is highly hygroscopic and susceptible to quick breakdown in ambient environments. This powder component must be opened and handled exclusively within an advanced glovebox atmosphere under dry inert conditions (H2O <1 ppm, O2 <1 ppm). Store far from high temperatures and localized humidity zones.
