This material is highly moisture-sensitive and must be stored under an inert atmosphere to prevent degradation. Exposure to ambient humidity can lead to hydrolysis and loss of electrochemical performance.
- Inert Atmosphere Requirement: Store and handle sodium bis(fluorosulfonyl)imide exclusively under an inert atmosphere such as argon or nitrogen.
- Moisture Protection: Keep the container tightly sealed when not in use and open only in a dry glovebox with moisture levels below 0.1 ppm.
- Temperature Stability: Maintain storage temperatures between 15°C and 25°C to prevent thermal decomposition.
- Oxidizer Incompatibility: Avoid contact with strong oxidizing agents to prevent exothermic reactions.
- Shelf Life Limitation: Use the material within the manufacturer's recommended shelf life after first opening to ensure consistent purity.
This protocol outlines safe transfer and dissolution of the moisture-sensitive salt under inert conditions. Proper glovebox technique ensures material integrity and avoids contamination or hazard.
Required Equipment: Inert atmosphere glovebox, Anhydrous electrolyte solvent, Precision weighing balance, Clean dry vial
- Transfer to glovebox
Transfer the sealed container into an argon-filled glovebox with moisture and oxygen levels below 0.1 ppm. - Weigh the powder
Weigh the required amount of sodium bis(fluorosulfonyl)imide powder into a clean, dry vial using a precision balance. - Dissolve in solvent
Add the powder to a pre-dried volumetric flask containing anhydrous electrolyte solvent and stir until fully dissolved. - Verify dissolution
Verify complete dissolution by visual inspection; the solution should appear clear with no visible particulate. - Seal and store
Seal the prepared electrolyte solution immediately and transfer it out of the glovebox for use.
How does the 99.95% purity and battery-grade moisture control of NaFSI affect its performance in sodium-ion battery electrolytes compared to lower-purity alternatives?
The 99.95% purity and strict battery grade moisture controls are engineered to prevent ambient degradation and ensure stable dissolution, which directly supports consistent electrolyte performance. Lower-purity NaFSI would introduce impurities and moisture that compromise solution integrity and electrochemical reliability, making this trade-off critical for high-demand battery systems.
What are the key compatibility constraints when formulating NaFSI into sodium-ion battery electrolytes?
NaFSI is optimized as a highly active imide salt core component for advanced battery electrolyte systems, and its white powder form provides predictable mass tracking and stable chemical dissolution during mixing. Compatibility is limited to formulations that maintain battery-grade moisture parameters; the product is intended for custom material design and high-performance electrolyte research without specified solvent restrictions.
What storage and handling protocols are required to maintain the battery-grade moisture specification of ATOMFAIR NaFSI?
NaFSI is supplied in an atmosphere-isolated high-integrity bottle that protects the solid white powder from ambient moisture. Storage should be in a dry environment, and the container must be resealed tightly after each use to preserve the battery-grade moisture controls. The 50g packaging is designed for laboratory research workflows, and prolonged exposure to open air should be avoided.
This battery-grade NaFSI salt offers 99.95% purity and strict moisture control, making it ideal for advanced sodium-ion electrolyte formulations, though it requires stringent dry handling and is limited to research-scale quantities.
Positive
- Ultra-high purity with moisture control: The 99.95% purity and battery-grade moisture parameters minimize impurities and water content, directly improving electrolyte stability and cycle life in sodium-ion systems.
- Consistent solid white powder matrix: The uniform solid morphology ensures predictable mass tracking and reproducible dissolution kinetics, critical for precise electrolyte formulation and consistent batch-to-batch performance.
Trade-offs
- Moisture-sensitive handling required: Despite battery-grade packaging, the material remains hygroscopic and must be stored and processed in dry, inert environments to prevent performance degradation from ambient moisture uptake.
- Limited to laboratory research scale: Sold exclusively for R&D workflows in a standard 50g package, which constrains high-throughput or pilot-scale deployment and necessitates sourcing for larger volumes separately.
