Handling and Procurement
Keep the container tightly closed in a cool, dry, well ventilated area, preferably under dry inert gas. Protect the material from moisture, water contamination, heat, and direct sunlight. Keep the container closed when not in use, and allow the material to reach room temperature before opening if condensation may occur. Review the SDS and use appropriate protective equipment before handling.

This ionic liquid is moisture-sensitive and requires storage under inert atmosphere to maintain its battery-grade quality. Handling must be performed in a dry environment, such as an argon-filled glovebox, to prevent moisture absorption and performance degradation.
- Moisture Sensitivity: This material readily absorbs atmospheric moisture, which can compromise its electrochemical stability and electrolyte performance.
- Inert Storage Requirement: Store the material under an inert gas atmosphere (argon or nitrogen) to keep moisture content at battery-grade levels.
- Glovebox Handling Protocol: Transfer and dispense the ionic liquid exclusively within a moisture-controlled glovebox to avoid ambient exposure.
How does the 99.9% purity and battery grade moisture specification of PY13-TFSI impact its electrochemical stability in battery electrolyte formulations?
The 99.9% purity and strict battery grade moisture control minimize trace impurities and water content that could catalyze decomposition at electrode interfaces, thereby preserving the ionic liquid's inherent high electrochemical stability. This reduction in side reactions directly supports consistent cycling behavior and longer calendar life in high-performance battery cells.
For which battery chemistries or electrolyte systems is PY13-TFSI (N-Methyl-N-propylpyrrolidinium TFSI) specifically formulated?
PY13-TFSI is formulated as a liquid component for high-performance battery electrolyte formulations, suitable for integration into lithium-ion, lithium-sulfur, sodium-ion, and solid-state systems. The 99.9% purity and battery grade moisture specification ensure compatibility with common lithium salts and carbonate or ether-based solvent mixtures used in these chemistries.
What handling and storage conditions are required to maintain the battery grade moisture level of PY13-TFSI after opening?
To preserve the battery grade moisture specification, PY13-TFSI must be stored in a tightly sealed container under an inert atmosphere (e.g., argon or nitrogen) and handled exclusively in a dry environment such as a glovebox. The product's hygroscopic nature requires that exposure to ambient humidity be strictly avoided, and the container be immediately resealed after each use.
This ionic liquid (PY13-TFSI) delivers 99.9% purity with battery-grade moisture control, making it a strong candidate for high-performance electrolyte formulations and advanced electrochemical research, though limited to 50g packaging and requiring stringent moisture-sensitive handling protocols.
Positive
- High purity with moisture control: The 99.9% purity and strict battery-grade moisture parameters minimize background contamination in sensitive electrolyte formulations, ensuring reproducible electrochemical performance.
- Optimized for electrolyte formulations: Specifically refined as a liquid component for high-performance battery electrolytes and advanced electrochemical process design, enabling consistent solution blending and reliable test results.
Trade-offs
- Limited to 50g packaging: Supplied in standard 50g packages, which may restrict large-scale or production-level trials, requiring multiple units for extended studies.
- Strict moisture sensitivity: The battery-grade moisture specification necessitates rigorous handling and storage in dry, inert conditions to prevent water uptake that could compromise electrolyte integrity.
