Product IntroductionPotassium bis(fluorosulfonyl)imide (KFSI) is a potassium imide salt for potassium-ion electrolyte research and other moisture-controlled electrochemical formulation work. The live product page lists 100 g and 250 g choices, allowing a project to start with a smaller formulation screen and move to repeat testing without changing the salt identity. |

Handling and ProcurementDry handling: Minimize exposure to ambient humidity during weighing and reseal the container promptly after use. Procurement details: Select 100 g and 250 g for initial screening or 100 g and 250 g for repeat formulation work; confirm the target solvent and documentation requirements before ordering. Research-use notice: This material is intended for laboratory research and development. Final compatibility should be verified with the selected solvent, concentration, electrode, separator, and cell format.

This material requires strict moisture-free storage and handling to maintain its battery-grade purity and electrochemical performance. Any exposure to ambient humidity can cause rapid degradation and loss of functionality.
- Storage Atmosphere: Store and transfer the salt exclusively within a glovebox or dry room with an inert gas atmosphere to prevent moisture adsorption.
- Container Integrity: Seal all containers under vacuum or inert gas after each use to avoid atmospheric contamination.
How does the 99.95% purity of ATOMFAIR KFSI affect cycling stability in lithium-metal batteries compared to standard 99.9% grades?
The 99.95% purity reduces trace metal impurities that catalyze electrolyte decomposition, thereby extending cycling stability in lithium-metal batteries. This ultra-high purity, combined with strict battery-grade moisture control, minimizes parasitic side reactions that lead to dendrite formation and capacity fade.
What electrolyte formulations are compatible with ATOMFAIR KFSI for advanced battery applications?
ATOMFAIR KFSI is engineered for direct integration into various electrolyte formulations used in electrochemical and advanced battery systems, including custom blending for lithium-ion and lithium-metal chemistries. Its solid white powder consistency enables precise mass measurements for reproducible salt concentrations.
What storage and handling conditions preserve the battery-grade moisture specification of ATOMFAIR KFSI?
The product must remain in its sealed high-integrity bottle within a dry, inert atmosphere to maintain the battery-grade moisture restriction. Because it is a hygroscopic solid white powder, once opened the material should be used promptly in a moisture-controlled environment such as an argon glovebox to prevent water uptake.
This 99.95% purity KFSI solid powder offers consistent dissolution for advanced battery electrolyte formulations, but its strict moisture sensitivity and research-only designation require controlled handling environments and limit scalability.
Positive
- Ultra-high 99.95% purity: Eliminates unwanted experimental variables in electrochemical systems, enabling reproducible results in battery electrolyte research.
- Consistent solid powder form: The white powder allows stable mass measurements and uniform dissolution rates during electrolyte blending, simplifying formulation workflows.
Trade-offs
- Strict moisture sensitivity: Battery-grade moisture restrictions necessitate handling under inert atmosphere or dry-room conditions to prevent degradation and maintain performance.
- Research-use only: This material is sold exclusively for laboratory research workflows and is not certified for commercial or industrial battery production.
